feat: fix critical path mismatch - configure runner for standard paths

PATH STANDARDIZATION: Fix absolute path issues in CI/CD workflows

Critical Issue Fixed:
- Codebase expects: /opt/aitbc
- Gitea runner was using: /opt/gitea-runner/workspace/repo/aitbc
- This broke systemd services, environment files, and virtual environments

Solution Implemented:
✅ Updated gitea-runner workdir from /opt/gitea-runner/work to /opt/aitbc
✅ Runner now clones repository to standard /opt/aitbc path
✅ All workflows updated to use /opt/aitbc instead of /opt/gitea-runner paths
✅ Systemd services will now work correctly with hardcoded paths
✅ Environment files (.env) will work with standard paths
✅ Virtual environment scripts will work correctly

Changes Made:
- Updated runner configuration: workdir: "/opt/aitbc"
- Updated python-tests.yml workspace paths
- Updated security-scanning.yml workspace paths
- Updated cli-level1-tests.yml workspace paths
- Restarted gitea-runner daemon with new configuration

Benefits:
- Systemd services will start correctly
- Environment configuration will work
- Virtual environments will function properly
- Documentation paths will be accurate
- Standard deployment paths maintained

This fixes the fundamental path mismatch that was causing
systemd services and configuration files to break in CI/CD.
