ReWork Notification Model/Module/Object/Repository/Factory

- Introduce Repository for interaction with "notify" table
- Introduce Factory for read-only notification objects (they're just loosely based on notification the table!)
- Introduce Objects for type-safe usage at the presentation layer
- Reworked Model, which is now fully based on the notify table, including generated fields (cache, ..)
