chore: remove legacy deployment files and update gitignore

- Removed .deployment_progress tracking file
- Removed .last_backup tracking file
- Removed AITBC1_TEST_COMMANDS.md and AITBC1_UPDATED_COMMANDS.md documentation
- Updated .gitignore for project reorganization (project-config/, docs/, security/, backup-config/)
- Enhanced .gitignore patterns for __pycache__, backups, and monitoring files
- Aligned gitignore with new directory structure from project reorganization
