ChrisBeWithYou 4db3db4622 v3 library: per-field pack overwrite (R4b) — fix wrong author values, with receipts
DRAFT — gated on the feedpak-spec §7 amendment (got-feedback/feedpak-spec#47).
Gap-fill (#724) fills absent keys; this fixes WRONG author-set values (a
typo'd artist, a wrong year) one field at a time, with provenance and an undo.
Built fully compliant with the amendment shape so it's ready the moment §7
is amended.

Server (extends the merged gap-fill endpoints, doesn't fork):
- Preview GET /api/song/{fn}/gap-fill now also returns `differs` =
  [{key, current, proposed}] over the allowlist (title/artist/album/year/
  genres) where the manifest HAS an author value and the confirmed match
  supplies a DIFFERENT one — plus `overwrite_allowed` (the Settings gate) and
  `has_backup`. differs is EMPTY unless match_state == 'manual': a
  user-confirmed pin can authorize a replace; an auto-match never can. mbid/
  isrc are never in differs (identity changes only via re-match).
- POST accepts `overwrite_keys` alongside gap-fill's `keys`; gated on the
  allow_pack_overwrite setting + manual state + the allowlist, proposals
  recomputed under _song_io_lock so a field that changed since preview is
  skipped. Writes via the re-serialize writer (extended to handle the genres
  list). Every written key (gap-fill AND overwrite) lands in a new write_log
  receipts table (filename, key, old, new, source, score, ts), pruned to the
  newest 5000 rows.
- POST /api/song/{fn}/revert-original restores the pack from its .bak (dir +
  zip forms), re-stats + re-syncs the DB; 404 when no backup; the .bak is
  PRESERVED after revert (re-appliable). Demo-blocked, like the write.
- GET /api/song/{fn}/write-log — the song's receipts, newest first.
- Setting allow_pack_overwrite (default OFF).

The .bak safety property is unchanged from the shipped writer: the backup is
written ONCE (first write) and is always the pristine author original — a
second overwrite never clobbers it, so Revert always returns the untouched
pack.

Frontend (Details drawer, extends the gap-fill block): when the preview
returns differs AND overwriting is enabled, an "Overwrite existing fields"
sub-block renders per-key rows `Artist: "ACDC" -> "AC/DC"`, ALL UNTICKED by
default, with the warning that it replaces what the author wrote and the
original is kept as a backup; the Write button carries the ticked keys. When
differs exist but the setting is off, one muted line points to Settings. A
"Revert file to original…" link (confirm dialog) appears whenever a backup
exists. Settings gains the allow_pack_overwrite checkbox.

Tests: tests/test_pack_overwrite.py — differs manual-only + identity-excluded
+ equal-skipped, refused when setting-off / not-manual / bad keys, dir + zip
overwrite, .bak stays the pristine original across a second write, write_log
records old+new (and gap-fills), prune at cap, revert dir+zip+404, demo
blocks write & revert. 30 pass with test_gap_fill green. node --check clean;
no new Tailwind classes.
