refactor: remove duplicate methods and improve DocMDP descriptions

- Remove duplicate getLabel() and getDescription() methods from DocMdpConfigService
- Use enum methods directly by passing IL10N instance
- Improve descriptions to differentiate between approval and certifying signatures
- Align descriptions with ISO 32000 DocMDP specification terminology

The new descriptions clearly distinguish:
- Approval signature (NOT_CERTIFIED): allows all modifications
- Certifying signature (levels 1-3): restricts modifications based on level
