Payment providers as classes (Strategy + factory); 10342 = monthly; health logs a failed Bazaar check

- payment/providers.py: ZarinpalProvider / BazaarProvider with one interface (check_plan, sku_for, payment_url,
  purchase_extras, discount_blocker, reconcile_user); provider_for / provider_for_method pick one; unknown fails.
  create_order, purchase view, discount redeem and reconcile_user_orders use it instead of scattered ifs.
- subscription.0015: Bazaar SKU 10342 on the one-month plan (owner: "probably the monthly one").
- config/health: the Bazaar check no longer swallows its exception without a log.
982 tests green.
