Replace the three always-visible 설정/알림/로그아웃 OutlinedButtons on the
repository list's top bar with a single hamburger-style overflow menu
("☰" IconButton + DropdownMenu). Same three callbacks, presentation-only
change, no icon library (plain Unicode glyph, matching this app's
established convention).
Build/test/lint green. Not yet live-verified on device — wireless
debugging was intentionally paused for this round per request.
