Making the library's tuning filter instrument-aware does not repair playlists
already built under the old guitar-first behaviour. Those keep their
wrong-tuning songs, so a player still hits a surprise retune mid-practice and
reasonably concludes nothing was fixed.
Adds a per-playlist check: each row is marked against the player's current
tuning, with a summary ("3 of 24 songs are not in your tuning"), a filter to
show only those, and an explicit removal that lists every affected song by
title and states they stay in the library. Flagging is the feature -- nothing
is ever removed without being asked for, and removal reuses the existing
per-song DELETE rather than adding a bulk destructive endpoint.
Reuses the tuner capability's coverage report and `window.feedBack
.workingTuning`, the same pair the library cards already score against,
rather than introducing another source of truth.
Two deliberate departures:
- A coverage report reads "not covered" both for a real mismatch and for a
bail-out it could not evaluate. Only a report carrying an actual reason
counts as a mismatch; the rest render as unknown. This differs from the
library grid, which paints every not-covered song amber -- acceptable on a
grid, not on a hand-curated playlist where a false warning costs trust.
- With no tuning perspective available it makes no claim at all, rather than
defaulting to guitar and reproducing the original bug in a new place.
Playlist rows carry `tuning_offsets` and `bass_only`; a tuning *name* cannot
be scored, since two "Custom Tuning" rows are different tunings.
Fully correct once the instrument-aware tuning filter lands. That dependency
is confined to `rowTuningForCheck()` in static/v3/playlists.js, marked SEAM.
