feat(telegram_bot): Add update_token command for mail API token management

- Add new /update_token command handler to update mail API token in config.toml
- Register command in handlers list and set_my_commands for bot menu
- Add command documentation to help text with usage example
- Implement token update logic with TOML file read/write operations
- Display masked token values (first 8 and last 4 characters) for security
- Add automatic config reload after token update
- Include error handling for missing tomli_w dependency and file operations
- Restrict command to admin users only via @admin_only decorator
