Merge branch 'main' into exp/orbit (pre-PR sync)

Conflicts resolved in:
- src/pages/SearchResults.tsx
- src/pages/AdvancedSearch.tsx

Both pages were rewritten on main (PR #303) to use the shared
<SongRow> component with click-to-enqueueAndPlay semantics. Orbit's
playSong helper that branched on orbit-active is no longer needed
at the page level — instead, orbit awareness moved INTO SongRow and
SongCard themselves: in an active orbit session both buttons collapse
into addTrackToOrbit (suggest for guests, host-enqueue for the host)
so we don't ship a queue replacement to every guest.

Also kept main's IntersectionObserver-based pagination on both pages.
