Phase 4b of the Search/Artists unification. Cin flagged that 'Artists'
in the sidebar read like a library section but was actually a
dedicated artist-search page, duplicating what unified Search already
does. Removed the sidebar entry so users funnel through Search.
- Sidebar Artists button gone
- 'Browse Artists' on empty Watchlist now opens Search
- 'View artist from Wishlist' opens Search pre-filled with the name
- Profile Home Page + Page Access drop the Artists option
artists.js stays on disk: it defines ~30 shared helpers used across
the app (escapeHtml, openDownloadMissingModalForArtistAlbum, service
status, download bubbles, image helpers) that library/discover/etc.
depend on. Wholesale deletion would orphan too much. The inline
Artists page and its selectArtistForDetail flow are still there —
just unreachable from the sidebar — so /artists deep links keep
working for bookmarks.
