feat(enrichment): AcoustID audio-fingerprint identification (opt-in) (#759)
* feat(enrichment): AcoustID audio-fingerprint identification (opt-in)

Text search can only guess the version; the definitive fix is content-based —
fingerprint the actual audio with Chromaprint (fpcalc) and look it up on
AcoustID, which maps the fingerprint to the EXACT MusicBrainz recording (the
approach Lidarr uses). Sidesteps the studio-vs-live ambiguity entirely.

- lib/acoustid_match.py: pure response parsing + config gating (unit-tested);
  normalizes AcoustID hits into the same candidate shape as mb_match so the
  review UI + editor Match popup render fingerprint and text hits identically.
- server.py: _fpcalc (Chromaprint subprocess), _acoustid_lookup (throttled,
  offline-guarded HTTP), _identify_by_fingerprint (also available to the
  library-enrichment pipeline), and POST /api/enrichment/identify (upload the
  master audio → candidates).
- Fully OPT-IN and graceful: absent the fpcalc binary or an ACOUSTID_API_KEY
  the whole path is a no-op / 503 and the text matcher runs unchanged.

Requires (both optional): the `fpcalc` (Chromaprint) binary on PATH/$FPCALC,
and a free AcoustID application key in $ACOUSTID_API_KEY. Pure parsing/gating
is unit-tested; the fpcalc + live-lookup path needs those two to exercise.

* feat(enrichment): make AcoustID self-serve — opt-in toggle + API key in settings

Fingerprinting was env-var only (ACOUSTID_API_KEY), so only an operator could
enable it. Add two core settings so a user can turn it on themselves:
  - acoustid_enabled (bool, default OFF — opt-in)
  - acoustid_api_key (string, ≤128 chars, trimmed; env var stays a fallback)

_acoustid_available()/_acoustid_lookup() now resolve (enabled, key) from
settings via _acoustid_settings(). /api/enrichment/identify distinguishes
"not set up" (412 needs_setup — the UI nudges the user to enable it) from
"set up but fpcalc/network missing" (503) so the client never fakes a match.

Verified: default off; POST round-trips + trims; 412 vs 503 gating; bad
types/over-length rejected. acoustid_match unit tests green (8/8).

* fix(enrichment): POST the AcoustID lookup instead of GET

A Chromaprint fingerprint is multi-KB (a 3.5-min track ≈ 3.5k chars), so
sending it as a GET query param overflows the request URL for longer songs and
fails spuriously. AcoustID accepts the same params form-encoded — POST them.

* fix(acoustid): space-separate the lookup `meta` (was silently dropping metadata)

The meta value was `+`-joined ("recordings+releasegroups+compress"). Sent over
the wire the literal `+` percent-encodes to %2B, which AcoustID does NOT split
into flags — so every hit came back with an empty `recordings` array and the
parser produced zero candidates (a fingerprint match that resolved to nothing).
AcoustID wants the flags space-separated. Verified against real fingerprints:
`+`-joined → 0 recordings; space-joined → 28, resolving Highway to Hell and
Living After Midnight to their canonical studio albums as the top hit.

* feat(acoustid): resolve the canonical original album + year from the fingerprint

AcoustID hits resolved the right recording but a weak album/blank year: the
album picker took the first studio-typed group (a later comp/soundtrack typed
"Album" could win) and the year took an arbitrary release (often a reissue).
Request the `releases` meta (which carries per-release dates) and use them to
(1) pick the EARLIEST original studio album among the groups and (2) fill the
year from that album's earliest release. Verified against real fingerprints:
Smoke on the Water → Machine Head (1972) not a later comp; Highway to Hell →
1979; Living After Midnight → British Steel (1980). +2 unit tests.

* feat(acoustid): per-song "Identify by audio" for the library metadata tooling

Add POST /api/enrichment/identify/{filename} — fingerprints an EXISTING library
song's own master audio (resolves the sloppak's original_audio or a loose
folder's audio), the library counterpart to the upload-based /identify used by
the editor. Wire an "Identify by audio" action into the match-review / Fix-match
modal: it renders fingerprint hits in the same candidate list and pins the pick
via the existing /review/{f}/pick. Shared _acoustid_gate() (412 needs_setup /
503) for both endpoints; 404 when a pack has no full mix. Both identify routes
added to the demo-mode block list (they spend fpcalc + the AcoustID budget) —
fixes a pre-existing miss on the upload route.

* fix(acoustid): regenerate stale tailwind CSS + cap identify upload

- static/tailwind.min.css was stale vs a fresh rebuild (ci/tailwind-fresh red);
  regenerated with the pinned tailwindcss@3.4.19 (byte-stable).
- /api/enrichment/identify read the whole multipart upload into memory before
  writing it; stream it to the temp file with a 256 MB cap (413 over) so an
  oversized upload can't balloon RAM. fpcalc reads from the temp file anyway.

* feat(acoustid): pre-parse upload guard + settings UI to enable it

- /api/enrichment/identify is now async: a pre-parse Content-Length check +
  request.form(max_part_size=…) reject an oversized body BEFORE Starlette spools
  the multipart to temp disk (mirrors the song-upload endpoint), and the blocking
  fpcalc subprocess + AcoustID HTTP run off the event loop via run_in_executor.
- The v3 Metadata-matching settings card gains an 'Identify by audio' opt-in
  toggle (acoustid_enabled, default OFF) + an AcoustID key input
  (acoustid_api_key), wired in match-review.js — so the advertised feature is
  reachable from the UI instead of only via a manual settings POST. Reuses
  existing classes only; committed tailwind.min.css stays fresh.
