feat(i18n): localize hardcoded UI strings and fix misspelled keys

Move remaining hardcoded English strings (player menus, technical-info
overlay, music/now-playing, live TV, TV search badges, MPV subtitle
settings, accessibility labels, not-found screen, session picker) to
en.json, and correct misspelled keys (occured -> occurred, autorized ->
authorized, liraries -> libraries, jellyseer -> jellyseerr) along with
their usages.
