test: add dual-parameter support and sync mocks for import/export tests

Update test infrastructure to support the dual app type parameter pattern
(app_type enum + app string) introduced in 590be4e:

- Add toast.warning mock for partial-success status handling
- Add syncCurrentProvidersLive mock to test post-import sync behavior
- Update MSW handlers to accept both app_type and app parameters with
  fallback resolution (app ?? app_type) across 7 provider endpoints
- Add sync_current_providers_live endpoint mock returning success

This ensures test compatibility during the app_type → app parameter
migration and enables testing of the new partial-success import flow.
