The prior fix for double-counting used an early-return guard that made
a repeat tap on an already-Starred row do nothing -- fixed the count
bug but also made the star impossible to undo from the ALL list.
Replaced it with a real toggle: an already-starred-this-session tap
now calls unstar() and decrements the count back down instead of being
inert.

toggleFavorite's ALL-list success branch updated favoriteAction to
Starred but never touched starsCount, so a row kept showing its
pre-star count even after the server had actually accepted it. Now
increments starsCount by 1 in the same update. Also guards against a
repeat tap on an already-Starred row (the ALL list can't tell a
repo's already-starred state on load, so the star stays tappable)
double-incrementing the displayed count.
