"""add biography_hu to plex_people — TMDB's Hungarian biography (E30 S4)

Revision ID: 0092_plex_person_biography_hu
Revises: 0091_plex_tagline_hu
Create Date: 2026-09-29

The person page showed a Hungarian reader the English biography although TMDB has a Hungarian one for
most people. The person fetch now appends `translations` and keeps the Hungarian biography beside the
English one. Already-enriched people are un-stamped, so their next page open refetches them once (the
same lazy path as a first open) and fills it; until then the English biography stands in.
