feat(tmdb): clickable director/creator chips and directing credits on person pages

Directors were plain merged text — no photos, no navigation — while the
data was already sitting in the cached TMDB payloads (credits.crew and
created_by both carry id + profile_path; they just were not typed or
parsed).

- tmdb-merge: enrichedDirectors (crew, job === 'Director', deduped by
  person id) and enrichedCreators (created_by) produce the same chip
  shape as the cast (TmdbEnrichedCastMember) into a new tmdb_directors
  field on all three merges (Xtream VOD, Xtream series, Stalker); types
  widened (crew id/profile_path, created_by id/profile_path).
- Detail views (shared VodDetailsComponent, Xtream vod/serial routes,
  Stalker series view) render the Director row as clickable avatar chips
  when tmdb_directors is present — same markup and openActor handler as
  the cast strip — falling back to the plain text otherwise. Stalker
  re-normalization allowlist preserves the new field.
- Person pages: mapPersonFilmography now merges combined_credits.crew
  (jobs Director/Creator) into the filmography — acting wins the
  per-title dedup, directing-only titles show the job in the character
  slot. Everything else (library matching, All-portals scope, filters,
  search fallback, back button) works unchanged because the person page
  is role-agnostic. Existing caches work as-is: crew/created_by were
  always part of the stored payloads.

Tests: merge spec (director/creator chips + crew-row dedup ×3 merges),
person spec (crew credits, Producer excluded, acting-wins dedup),
stalker-vod.utils passthrough. Docs updated (CLAUDE.md + architecture).
