fix(security): resolve CodeQL vulnerabilities and license issues

- Replace insecure URL substring matching with proper URL validation
- Use URL.hostname for localhost detection instead of .includes()
- Add word boundary anchors to HTTP URL regex patterns
- Remove TruffleHog action due to AGPL-3.0 license incompatibility
- Add MIT-0 and CC0-1.0 to allowed licenses for CSS tools
- Update npm audit level to 'high' across all security workflows

Fixes:
- Incomplete URL substring sanitization (HIGH)
- Missing regular expression anchor (HIGH)
- License compatibility issues with dependency review
