fix(i18n,a11y): sync <html lang> + dir with i18n language

Browse Source 
index.html ships <html lang='ru'> and that attribute never changed at
runtime, regardless of the user's selected language. Consequences:
- screen readers pronounced en/zh/fa content using Russian phonics
- browsers offered to translate already-translated content
- the Telegram login button and an OAuth widget read documentElement.lang
  to set their own locale and got the wrong one

LanguageSwitcher had a half-fix that only touched dir for fa, and only
locally — i18n changes from anywhere else (initial detect, Telegram
adopt) were not covered.

Move both lang and dir updates into a single languageChanged subscriber
inside i18n.ts, run once for the initial detected language, and drop
the now-redundant dir-setting in LanguageSwitcher. Layout direction
flips automatically for the full RTL set (fa + future ar/he/ur).
