feat(validation): centralize validation patterns for names and descriptions

- Introduced `ValidationPatterns` class to standardize validation rules and messages for name and description fields across the application.
- Updated various components and models to utilize the new validation patterns, ensuring consistent sanitization and validation logic.
- Replaced the `HasSafeNameAttribute` trait with `HasSafeStringAttribute` to enhance attribute handling and maintain consistency in name sanitization.
- Enhanced the `CleanupNames` command to align with the new validation rules, allowing for a broader range of valid characters in names.
