Refactor configuration handling and add mail management features

- Removed dependency on messages package in TOML loading and parsing.
- Introduced new config constants and messages for better clarity and maintainability.
- Implemented mail user and mailbox management with corresponding controllers and views.
- Added new templates for mailboxes, mailbox creation, and user management.
- Enhanced logging and error handling throughout the application.
- Established a structured approach for applying default values in TOML configuration.
- Created new utility functions for SMTP and email handling.
