feat(blocking): account-deleted recovery screen with bot deep-link

Pairs with backend feat(deleted-users) — when the cabinet returns
403 {detail: {code: 'account_deleted', message, bot_username,
telegram_deep_link}} the SPA shows a dedicated screen instead of the
generic auth-error toast.

* Adds AccountDeletedScreen with localized title/description, an
  Open-bot button using the backend-provided telegram_deep_link, and a
  Retry button that clears the block + reloads (so the next request
  observes the now-revived row).
* useBlockingStore gains accountDeleted slice mirroring the existing
  maintenance/channel-subscription/blacklisted slots — consistent with
  the precedent for cross-cutting 403 codes.
* apiClient: AccountDeletedError type + isAccountDeletedError guard +
  response interceptor routes the 403 into the blocking store.
* i18n: ru/en/zh/fa parity for title, description, openBot, retry, hint.

No behavior change for ACTIVE users. BLOCKED users still get the
generic 403 (the backend keeps the message opaque for admin actions).
