Localize remaining hardcoded UI strings and persist language preference

Replaces the last hardcoded English strings (initial-scene modals, game
menu save status messages) with locale-loaded text, adds a shared
LOCALE_LIST so the settings dropdown and locale manager stay in sync,
and persists the chosen language into savemeta_t across all platforms.
Also fixes two message buffers that were too small for their longest
translations.
