fix(node): stop a movie with a mangled quality tag being shelved as a series

Found on demo35: "Some.Film.2017.MULTI.108.grp.mkv" — the release name's
"1080p" truncated to "108" — makes guessit read S01E08, so enrich.py's
flat-library branch (elif ep.episode is not None) filed a standalone film
as a series. "Fix match" then only offered TV results for the phantom
show, so there was no way out from the UI.

- title_parse.has_episode_marker(): true only for an explicit SxxExx /
  1x08 / "Episode N" / "Season N" token, not a bare 3-4 digit run.
- enrich.py: the flat-library branch now needs ep.season AND ep.episode,
  plus either a real marker or the absence of a "(2019)"-style year.
  Every genuine flat-dumped episode in the corpus carries a marker, so
  real shows are untouched; the same misparse on "1280" ("...2013.1280...")
  is covered too.

docs/mediacenter.md §10.2. Known gap left open: no operator control over
the movie/show kind itself — a "this is a movie / a show" toggle would.

+### 10.2 A movie mis-shelved as a series (2026-08-29)
+
+`Some.Film.2017.MULTI.108.grp.mkv` — a movie whose `1080p` tag was truncated to `108` —
+made guessit invent `S01E08`, so `enrich.py`'s flat-library branch filed a standalone film
+as a nonexistent series, and "Fix match" (TV-only for a "show") could only offer other
+series. **Fixed** (`fix/movie-misclassified-as-show`): that branch now requires
+`ep.season` *and* `ep.episode`, plus either an explicit marker
+(`title_parse.has_episode_marker` — `SxxExx` / `1x08` / `Episode N` / `Season N`) or the
+absence of a `(2019)`-style year; otherwise it falls through to the movie branch. A real
+flat-dumped episode always carries a marker, so nothing regresses.
+
+**Still open:** there is no operator control over the movie/show classification itself —
+"Fix match" only changes the TMDB id, not the kind. A genuinely ambiguous name
+(`Show.2019.308.mkv`) that guessit slots wrongly has no in-UI remedy short of renaming the
+file. A "this is a movie / a show" toggle would close that.
