feat: Enhance notification service configuration and refactor related components

- Updated notification service models to use pointers for boolean fields, allowing for better handling of enabled states.
- Introduced helper methods for getting and setting enabled states in notification and auth provider models.
- Refactored notification form templates to consolidate event trigger handling, improving code maintainability.
- Added SSL verification configuration to the application settings, allowing users to skip SSL verification for outgoing notifications.
- Enhanced the notification sending logic to respect the SSL verification setting.
- Introduced new migration to alter boolean defaults in the database schema for better compatibility with the updated models.
- Added unit tests for email and Rclone service functionalities to ensure reliability.
