* fix(tmdb): stop a broken provider tmdb_id from suppressing enrichment
Providers ship dead and stale tmdb_id values, and enrich() trusted them
unconditionally:
parseProviderTmdbId(query.tmdbId) ?? await resolveIdBySearch(...)
A garbage-but-integer id short-circuited the title search entirely. The
details fetch then 404'd, the outer catch swallowed it, and the item was
left permanently unenriched — no plot, no cast, no artwork — for a title
the search would have matched. Failed detail fetches cache nothing, so
the wasted request repeated on every re-open. The stale-but-valid case
was worse: it never threw, nothing sanity-checked the resolved title, and
we confidently rendered another film's metadata.
enrich() now treats the provider id as a hint. If it fails to resolve, or
resolves to something whose title matches none of the search variants we
would have queried, the confidence-gated title search gets its turn — and
proven-bad ids are negative-cached (7d, language-independent row) so the
404 is not repeated forever.
Deliberately NOT a hard rejection on title mismatch: TMDB returns titles
in the REQUEST language, so a Russian provider title legitimately fails
the name check against an en-US payload. A mismatch only lets the search
compete; when the search finds nothing confident, the provider payload is
kept. The change can therefore only add enrichment, never remove it.
Extracts the search resolution and the bad-id cache into
TmdbIdResolverService — tmdb-enrichment.service.ts was at 290 lines
against the 300-line target, and the resolver is independently testable.
Tests: new tmdb-enrichment.service.spec.ts covers the happy path issuing
exactly one details call and no search, 404 fallback, stale-id override,
the keep-the-payload safety property, bad-id skip, and the no-match case;
matcher spec covers detailsMatchProviderTitle and the namespaced cache key.

* fix(tmdb): only blame a provider id when TMDB confirms it does not exist
Review found the bad-id negative cache too eager in two ways, both of
which could deny enrichment to items whose id was fine.
1. Any failure recorded the verdict. A 401, 429, 5xx or an offline blip
would mark a perfectly valid id as dead for seven days, so after the
service recovered — or the user fixed their API key — titles that the
search cannot resolve confidently stayed unenriched until the marker
expired. TmdbApiService now throws a typed TmdbApiError carrying the
status, and only a confirmed 404 is recorded.
2. Title mismatches were recorded too. That id EXISTS; it is merely wrong
for this item. The row is keyed by id alone and shared across
playlists, so a stale mapping on one item disabled the direct lookup
for every other item that legitimately used the same id. Mismatches
are no longer cached at all — the search verdict is cached anyway, so
the repeat cost is a single details fetch.
Documents the row kind in the cache contract, which listed only two of
the (now six) lookup_key shapes.
Tests: 404 records, 429 does not, network error does not, mismatch does
not.

* fix(tmdb): keep provider details when the competing search fails
detailsForProviderId only runs the search to see whether it can beat a
title-mismatched provider payload. A throw from that best-effort search
(offline, rate limit, 5xx) propagated to enrich()'s outer catch and threw
away details we already had — the searched-details fetch right below it
was already tolerant. Fail to the details in hand instead.

* fix(tmdb): decide a suspect provider id on evidence, not on the title
The title check alone was both too weak and too dangerous.
Too weak: normalizeTitle strips trailing years, so "Blade Runner 2049"
carrying the 1982 film's id matched and the wrong film was rendered —
exactly the stale-id case this was meant to catch.
Too dangerous: an ALL-CAPS leading token reads as a language tag, so
"IT - Chapter Two" normalizes to "chapter two". The correct payload
failed the name check, and a year-less search for "chapter two" would
confidently return the 1979 film and overwrite it. Master trusted the
provider id here and got it right.
assessProviderId weighs both signals: title or year agrees means use the
details; both years known and incompatible means the search may take
over; a title-only mismatch is inconclusive and keeps the details. The
search branch now always has a year, so its own gate corroborates
whatever it returns instead of matching on name alone.

* fix(tmdb): do not search after a transient provider-id failure
enrich() reads a null from detailsForProviderId as "the id is unusable,
try the search". A 401/429/5xx/offline failure gave it that null, so an
outage turned into a second request that would fail too — and if it did
come back, a title match replaced a provider id that was probably fine.
Only a 404 falls through to the search now; everything else rethrows and
leaves the id retryable.
