feat: delete actions for warehouse/reservations/coupons/customers + Koja listing toggle

Delete (every manageable entity that only had "add" now has delete):
- Ingredients (warehouse): new DELETE /inventory/ingredients/{id} (soft-delete via
  the global DeletedAt filter — no FK trouble with recipes/movements) + NoOp stub +
  trash button in the materials cards.
- Reservations: new DELETE /reservations/{id} (soft-delete) + per-card delete button.
- Coupons & Customers: backend DELETE already existed; wired delete buttons in the UI.
- Shared ConfirmDialog component used by all delete flows (RTL-aware).
- Audit result: tables/branches/taxes/kitchen-stations/expenses/menu/terminals already
  had delete; HR has no "add" so no delete needed; shifts intentionally excluded
  (financial open/close records, not add-style entities).

Koja visibility:
- New Cafe.ShowOnKoja flag, default TRUE (DB default true so existing cafés stay
  listed). Discover query now filters IsVerified && !Deleted && ShowOnKoja.
- public-profile GET/PUT expose showOnKoja; dashboard public-profile panel has an
  on-by-default toggle that persists immediately. Platform IsVerified gate unchanged.
- EF migration AddCafeShowOnKoja (defaultValue: true).

Also: added the missing errors.generic i18n key (fa/en/ar) so useApiError's fallback
resolves instead of rendering the literal "errors.generic". 81 API tests pass.
