Sort repositories by recent push, page the list, show last-pushed branch

TASK-017, human product owner priority-1 request. Repository list now
requests sort=updated&order=desc from Gitea, loads 5 repositories per
page with explicit prev/next navigation, and each visible row
independently fetches and shows its most recently committed branch.

Removes the legacy eager-loading RepositoryListApi in favor of the
existing paged GiteaRepositoryBrowser.listRepositories. Fixes two
issues found in self-review: missing error handling on page
navigation, and repositories with no default branch (empty repos)
previously failing the whole page instead of just that row.

+## 2026-08-26 — TASK-017: recent-push sort, paged repository list, last-pushed branch
+
+- Agent and role: Claude, feature implementer, per human product owner priority-1 request in conversation on 2026-08-26.
+- Commit/diff: branch `claude/task-017-recent-push-favorites` from `fdda164`; new task file `tasks/017-repository-list-recent-push.md`.
+- Features implemented: Repository list is now sorted most-recently-pushed-first (server-side `sort=updated&order=desc`, correct across page boundaries), paged 5 at a time with explicit previous/next navigation, and each visible repository independently shows (and can retry) its most recently committed branch.
+- How it was implemented: Added `updatedAtEpochMillis` to `RepositorySummary` and `commitAtEpochMillis` to `BranchSummary`, mapped from Gitea's `updated_at` and branch `commit.timestamp`. Replaced the legacy eager-loading `RepositoryListApi`/`AccessibleRepositoriesGateway` with the existing paged `GiteaRepositoryBrowser.listRepositories`. `RepositoryListViewModel` now tracks a page number and launches one cancellable job per visible row to fetch and compare that repository's branch timestamps; jobs are cancelled on page change/refresh/navigation-away and resumed (not restarted) when returning via back-navigation.
+- Files changed: `domain/model/RepositoryModels.kt`, `data/repositories/GiteaRepositoryBrowserApi.kt`, removed `data/repositories/RepositoryListApi.kt` and its test, `feature/repositories/RepositoryListViewModel.kt`, `feature/repositories/RepositoryListScreen.kt`, `MainActivity.kt`, `strings_repositories.xml`, associated tests, `tasks/017-repository-list-recent-push.md`.
+- Checks and results: `assembleDebug testDebugUnitTest lintDebug --rerun-tasks` BUILD SUCCESSFUL — 105 unit tests across 22 suites, 0 failures/errors, 0 lint errors; `git diff --check` clean (CRLF notices only); sensitive-pattern scan clean.
+- Review findings and resolutions: Self-review caught and fixed two issues before they shipped: (1) page-navigation/refresh calls had no `try`/`catch`, which would have crashed the app on any network failure during `nextPage()`/`previousPage()`/`refreshRepositories()` — wrapped in the same error-mapping pattern used elsewhere; (2) a repository with no default branch (a real Gitea state for empty repos) would have failed the entire page load via the existing fail-closed `.required()` mapping — `defaultBranch` is now nullable at the domain level, matching how the UI already handled it. Independent Codex review is pending.
+- Known limitations: No physical device was available to verify page navigation and per-row branch loading interactively. Timestamp ties between two branches resolve deterministically but arbitrarily (first match kept).
+- Next recommended task: TASK-018 (Gitea-star favorites tab), already scoped in `tasks/018-favorites-gitea-star.md`, is next; Codex review of TASK-017 can happen in parallel since it touches non-overlapping paths once merged.
+- Next owner: Codex for read-only review of TASK-017; Claude continuing to TASK-018.

+# TASK-017: Sort repositories by recent push, page the list, and show the last-pushed branch
+
+Status: implemented; all required checks pass; pending Codex review
+Owner: Claude (human product owner priority-1 request, 2026-08-26)
+Reviewer: Codex
+
+## Outcome
+
+The repository list shows the signed-in account's repositories most-recently-pushed first, loads them a page at a time instead of eagerly loading everything, and shows each visible repository's most recently pushed branch.
+
+## Scope
+
+- Included:
+  - Add `updatedAt` (Gitea `updated_at`) to `RepositorySummary` and request server-side `sort=updated&order=desc` so ordering is correct across pages.
+  - Replace the legacy eager-loading `RepositoryListApi`/`AccessibleRepositoriesGateway` (which pages internally and returns one aggregated list) with the existing paged `GiteaRepositoryBrowserApi.listRepositories(page, pageSize)` from TASK-004, wired through the domain `Page<RepositorySummary>` contract.
+  - Reduce the repository list page size to 5 (human product owner decision, 2026-08-26) with explicit load-more/pagination UI, replacing today's single unpaginated load.
+  - Add `commit.timestamp` to `BranchSummary` (mapped from Gitea's branch-list `commit.timestamp` field) and, for each repository visible on the current page only, fetch its branches and surface the one with the latest `commit.timestamp` as "last pushed branch."
+- Excluded:
+  - Any write/mutation of repository or branch state.
+  - Favorites/starring (TASK-018).
+  - Sorting or paging the branch/tag list itself (already paged; unaffected).
+

+
+## Acceptance criteria
+
+- [x] Repository list requests `sort=updated&order=desc`; ordering is correct across page boundaries (verified by a fake-transport test asserting the query parameters, not by trusting client-side re-sorting).
+- [x] `RepositorySummary.updatedAt` is populated and covered by DTO-mapping tests (present, absent/malformed → typed failure, consistent with existing `.required()` fail-closed pattern).
+- [x] The repository list screen loads 5 repositories per page with explicit next-page loading; no behavior change for accounts with 5 or fewer repositories.
+- [x] The legacy `RepositoryListApi`/`AccessibleRepositoriesGateway` code path and its now-unused tests are removed once the ViewModel is migrated to `GiteaRepositoryBrowserApi.listRepositories`; no duplicate repository-list implementation remains.
+- [x] Each of the 5 visible repository rows independently fetches and displays its last-pushed branch name once available; a slow or failed per-row branch fetch does not block or fail the rest of the page, and is retried independently.
+- [x] Repository row branch-timestamp fetches are cancelled when their row scrolls out of the current page/is replaced by a refresh, to avoid orphaned requests (races/cancellation, matching the existing `startOperation` pattern).
+- [x] Loading, empty, offline, authentication-expired, and server-error states remain accessible and localized for both the repository page and the per-row branch fetch.
+- [x] Tests cover: sort/pagination query construction, page-boundary correctness, per-row branch-timestamp selection (including a repository with zero branches, and a tie on identical timestamps), and cancellation on row replacement.

+
+## Evidence
+
+Implemented on branch `claude/task-017-recent-push-favorites` from commit `fdda164` (TASK-004/005/006 reviewed-and-frozen base).
+
+- Domain: `RepositorySummary` gained `updatedAtEpochMillis: Long`; `defaultBranch` changed from non-null `RepositoryRef` to nullable `RepositoryRef?` (an empty/newly-created Gitea repository can have no default branch — previously this threw `ApiFailure.InvalidResponse()` for the *entire* page instead of marking just that one repository, a latent bug surfaced by routing the main list through the already-existing TASK-004 paged endpoint). `BranchSummary` gained `commitAtEpochMillis: Long`.
+- Data: `GiteaRepositoryBrowserApi.listRepositories` now requests `sort=updated&order=desc` and maps `updated_at`; `listBranches` maps `commit.timestamp`. A shared `String.toEpochMillisOrInvalid()` helper replaced three near-duplicate `Instant.parse`/catch blocks (also used by `mapCommit`, no behavior change there).
+- Removed `RepositoryListApi.kt`/`AccessibleRepositoriesGateway`/`AccessibleRepository` and their test file — this was a second, independent repository-list implementation with its own internal eager-all-pages loop; the ViewModel now uses only `GiteaRepositoryBrowser.listRepositories`.
+- `RepositoryListViewModel`: repository loading is now page-based (`REPOSITORY_PAGE_SIZE = 5`) with `nextPage()`/`previousPage()`/`refreshRepositories()`. Each visible row launches its own cancellable branch-fetch job (tracked in `rowBranchJobs`, keyed by `RepositoryCoordinates`) that pages through that repository's branches and picks the maximum `commitAtEpochMillis`; `Content` rows carry a `LastPushedBranchUiState` (`Loading`/`Loaded`/`Empty`/`Failed`). Row jobs are cancelled and relaunched on every page load/refresh (`cancelRowBranchJobs()` at the top of `loadRepositoryPage`) and cancelled on navigating away to references or logging out; `backToRepositories()` resumes only rows still `Loading` rather than restarting completed ones. A row's `AuthenticationExpired` failure clears the session the same way every other authenticated call does, instead of being swallowed as a per-row `Failed` state. `retryRowLastPushedBranch` retries a single row without touching the rest of the page.
+- UI: `RepositoryListScreen`'s repository list gained a refresh button, a per-row last-pushed-branch line (with localized loading/empty/failed+retry states), and a previous/page-number/next footer row, all localized (`strings_repositories.xml`).
+- `MainActivity` passes `repository.coordinates` directly instead of re-validating owner/name through `RepositoryCoordinates.of` a second time.

+
+Known limitations:
+- No physical device was available; page navigation, per-row branch loading, and the removed legacy path have not been manually verified on-device.
+- Tie-breaking when two branches share the exact same commit timestamp is deterministic (`maxByOrNull` keeps the first match) but arbitrary from a product standpoint; acceptable since this is a rare edge case and not user-configurable.
