Khalid Abdi d237504af9 frontend: add Somali, Arabic (RTL) & German languages
Add three UI locales (so/ar/de) with full ~1,660-key translations alongside
en/fr, selectable in Settings → Profile. Arabic gets full right-to-left support:

- config.ts registers the locales and exports a `dirFor` helper; an inline
  <head> script in layout.tsx sets <html dir/lang> before first paint (no RTL
  flash), and i18n-provider keeps them in sync on language change.
- ~160 physical direction utilities converted to logical (ms/me/ps/pe/
  start/end/text-start/text-end); directional chevrons/arrows get rtl:rotate-180;
  chat-bubble align variants fixed to logical.
- IBM Plex Sans Arabic appended to the sans/heading font stacks for
  per-character Arabic fallback.
- Language persists to the backend user_settings and re-applies on sign-in so it
  roams across devices (localStorage stays the offline source of truth).
- New scripts/check-locales.mjs (npm run check-locales) enforces key/placeholder
  parity and Arabic CLDR plural completeness.

Bump to 0.3.0.
