faith: progressive enhancement for all faith pages without JS

- Rosary: mystery selection, luminous toggle, and latin toggle fall back
  to URL params (?mystery=, ?luminous=, ?latin=) for no-JS navigation
- Prayers/Angelus: latin toggle uses URL param fallback
- Search on prayers page hidden without JS (requires DOM queries)
- Toggle component supports href prop for link-based no-JS self-submit
- LanguageSelector uses <a> links with computed paths and :focus-within
  dropdown for no-JS; displays correct language via server-provided prop
- Recipe language links use translated slugs from $page.data
- URL params cleaned via replaceState after hydration to avoid clutter
