[glm-grade=B+] feat(i18n): complete card/filter/action translation keys for 31 languages

Full language display names + RTL set (ar/fa/ur) on /i18n/languages;
card.internet/auth/tailscale/dashca, status pills, filter bar and
batch-operation strings added to every language dictionary. Frontend:
English now loads the server dictionary too (keys are semantic ids,
not fallback copy), failed loads keep existing DOM text instead of
exposing raw keys, isLoaded() gate for pre-load renders. Rebuilt
status/dist. Tests: i18n-cards 9/9, full suite 1837/1837.
