Add log cleanup function (15-day deletion) and archive documentation
- Added cleanup_old_logs() function to app_v3_simplified.py - Deletes log.txt if older than 15 days at app startup - Sends notification to monitoring server when cleanup occurs - Archived all legacy modules and documentation to oldcode/ - Updated device_info.txt with correct IP (192.168.1.104) - All changes validated and tested
