feat: Persian panel/API fixes and structural-model tweaks

- lang/fa: add validation/auth/passwords/pagination translations so admin
  and API validation errors are in Persian
- templates: soft-delete instead of cascade-deleting their generations;
  keep resolving trashed template on generations (labels/downloads)
- templates: add TemplateInfolist with a real thumbnail ImageEntry
- generations: auto-name template-based generations and use that name
  for the download file and as a searchable column
- admin: show all dates as Jalali via ->jalaliDate()/->jalaliDateTime()
  Filament macros (App\Support\Jalali)
- wallets: harden the deposit/withdraw action to surface the exact error
  instead of a 500
- profile: normalize Iranian mobile numbers (App\Support\Mobile),
  add social_links, coerce notification-preference booleans, require the
  current password to delete an account
