- Added `clean_name` function to `validation.py` for name validation with max length. - Simplified docstrings in `dnsx` client, parser, and service files for clarity. - Enhanced error handling in `ViewDNSService` to prevent disabling keys on rate limits. - Improved WHOIS service to handle concurrent inserts gracefully with integrity checks. - Updated `Settings` class in worker config to inherit from `BaseAppSettings`. - Added new dependencies in `pyproject.toml` for `apprise` and `cryptography`.
