Phase 128 complete:
- add Erli /inbox order import with safe mark-read ACK
- add cron/manual import controls and sync state tracking
- map Erli orders into orderPRO aggregates with mapper tests and docs
- Add IntegrationSources {ALLEGRO, SHOPPRO, APACZKA, INPOST} and RedirectPaths constants in src/Core/Constants/
- Replace integration source literals in AllegroOrderImportService, AllegroStatusSyncService, ShopproOrdersSyncService, ShopproPaymentStatusSyncService
- Replace redirect path literals in AllegroIntegrationController (24+ occurrences) and ShopproIntegrationsController (3 occurrences)
- Auto-fix: broken use statements from plan 06-01 in AllegroOrderImportService and AllegroIntegrationController (missing backslashes)
