refactor(library): share the track selection bar and delete action

The Library list's multi-select toolbar (FLAC upgrade, re-enrich, convert, ReplayGain add/remove, delete) becomes LibraryTrackSelectionBar, and its delete flow becomes deleteLibraryTracks. The Library list renders and behaves as before; other screens can now offer the same actions.
