fix: sidebar accordion + koja slug + support ticket LINQ crash

Sidebar:
- All groups start collapsed on first load (v4 storage key resets old state)
- Opening one group closes all others (accordion)
- Navigating to a section opens only that section's group

Koja slug:
- SlugHelper: Persian->Latin transliteration, slug validation
- Registration accepts optional custom slug; auto-derives from cafe name
- Slug can be updated from dashboard Settings -> Profile
- Settings PATCH validates uniqueness (SLUG_TAKEN) and format (INVALID_SLUG)
- koja.meezi.ir/{slug} now redirects to /fa/cafe/{slug} (short URL support)

Bug fix:
- SupportTicketService: cafeId/status filters applied before Select() projection
  to fix EF "could not be translated" crash on the support tickets page
