fix(git): close Issues/PR feed top gap; add "Mine" repo feed filter

The status feed drew its filter-chip header at the top of the content area
(under the disappearing top bar) while the feed's LazyColumn separately
re-applied the full bar-height inset as content padding, leaving an empty
band above the first item. The header now consumes the scaffold top inset
itself and the inner feed renders with the top inset zeroed, matching the
Code tab's padding pattern.

Also adds a "Mine" option to the git repositories top-nav filter so the
feed can show only the logged-in user's own repositories. The feed side
already resolves TopFilter.Mine generically; this just exposes it via a
dedicated gitRepositoryRoutes catalog (kind3 + Around Me + Global + Mine).
