[areyeslo]

• Add CRUD operations for notifications.
• Add validation that only one file id and sub-id is added during creation:

---------------------------------------------------------------------------
| Subtype                     | File                                      |
---------------------------------------------------------------------------
| AGREEMENT_ID                | ACQUISITION_FILE_ID or DISPOSITION_FILE_ID |
| LEASE_CONSULTATION_ID       | LEASE_ID                                  |
| LEASE_RENEWAL_ID            | LEASE_ID                                  |
| NOTICE_OF_CLAIM_ID          | ACQUISITION_FILE_ID or MANAGEMENT_FILE_ID |
| INSURANCE_ID                | LEASE_ID                                  |
| EXPROP_OWNER_HISTORY_ID     | ACQUISITION_FILE_ID                       |
| TAKE_ID                     | ACQUISITION_FILE_ID                       |
---------------------------------------------------------------------------

• Add privacy, only the notification user can retrieve, update or delete their own notification .
• Validate that sub-ID is assigned to FileID.
