Integrate the community-contributed Hungarian translation by
Tibor Hermann (@htibcsike) as the 19th locale:
- add apps/web/src/assets/i18n/hu.json (1,142 of 1,175 keys translated;
32 keys added after the contribution fall back to English, plus the
new LANGUAGES.HUNGARIAN endonym)
- register HUNGARIAN = 'hu' in the Language enum, SUPPORTED_LANGS,
Angular date locale registration, and the TMDB language map (hu-HU)
- add LANGUAGES.HUNGARIAN = "Magyar" to en.json and all other locales
via tools/i18n/fill-missing.mjs
- update README.md and CLAUDE.md language counts to 19
Closes#1192, refs #1140.
