feat(node,hub): season-specific overviews, manual TMDB match correction, and wizard polish

Two operator-facing fixes for a real 3-season show whose automatic TMDB
match was wrong at the show level: per-season overview/air_date tabs in the
detail modal (falling back to the show-level text when a season's own is
empty), and a "Fix match…" search-and-correct affordance that re-resolves
every file sharing the corrected show's display_title. New signed op
OP_TMDB_OVERRIDE and two read-only pairs (season_meta_req/resp,
tmdb_search_req/resp), MNP_VERSION 0.5 -> 0.6.

Also: the create-group wizard gets a spinning indexing indicator and an
app-selection step, group settings default the TMDB language to the
operator's own locale (never as a global default), and a file renamed
mid-session now re-triggers title parsing instead of being silently
skipped by the enrichment dedup guard.

Fixes two bugs found during this work: the search overlay's z-index lost
to the base video-overlay class and rendered invisibly, and season_meta's
own empty overview didn't fall back to the show-level one.
