fix: update safety command from deprecated 'check' to 'scan'

DEPRECATION FIX: Replace deprecated safety check command

Issue: 'safety check' command deprecated, will be unsupported beyond June 2024
Warning: 'DEPRECATED: this command (check) has been DEPRECATED'
Recommendation: Switch to new 'scan' command which is easier and more powerful

Changes:
- Replace 'venv/bin/safety check' with 'venv/bin/safety scan'
- Update debug messages from 'Safety check' to 'Safety scan'
- Maintain all other functionality and error handling
- Apply to all workflows using safety tool

Updated workflows:
- fix.yml: safety scan for dependency security
- security-scanning.yml: safety scan for comprehensive security

Expected results:
- No more deprecation warnings
- Using modern safety scan command
- Same security functionality with improved tool
- Future-proof security scanning

This ensures the workflows use current, supported security tools
and avoid deprecation warnings.
