fix(notifications): update Mattermost notification handling

- Changed webhookUrl validation to ensure it is a valid URL.
- Updated input types for createMattermostNotification and updateMattermostNotification functions to use z.infer for better type inference.
- Refactored sendMattermostNotification to improve error handling and payload construction.
