Enhance notification search functionality and update API documentation

- Added `search` and `q` query parameters to the `SearchForm` for improved notification searching capabilities.
- Implemented `ResolvedSearch` method to prioritize search term resolution from the new parameters.
- Updated `GetByUserID` repository method to support searching notifications by title and message using regex.
- Enhanced logging in the `GetNotifications` service method to include search parameters.
- Updated Swagger documentation to reflect the new search parameters for the notification API.

This update improves the user experience by allowing more flexible and efficient searching of notifications.
