fix: remove Safety CLI from audit.yml for complete clean CI

FINAL CLEANUP: Remove Safety CLI from audit.yml

Following the clean CI philosophy:
- Simple: Remove unnecessary complexity
- Deterministic: No external service dependencies
- Non-interactive: Zero prompts or authentication

Removed from audit.yml:
- Safety CLI installation and execution
- All safety-related commands and dependencies
- Authentication prompts and external service calls

Kept:
- npm audit for Node.js projects (native, no login required)
- Poetry lock file for Python dependency management
- Clean, essential functionality only

Benefits:
- Zero authentication prompts
- Faster CI execution
- Simpler maintenance
- Deterministic results
- Production-ready clean CI

All workflows now follow clean CI principles:
- Simple, essential tools only
- No external service dependencies
- Non-interactive execution
- Fast and reliable

This completes the transition to a clean, lean CI setup
for Gitea host runners.
