🔧 Fix machine connectivity and pharmacy display issues

- Fix database initialization to use correct Headscale DB path
- Implement proper data synchronization between Headscale and FARMQ
- Resolve timezone comparison error in machine online status detection
- Update machine listing to use actual Headscale Node data instead of MachineProfile
- Add proper pharmacy-to-machine mapping display
- Show both technical Headscale usernames and actual pharmacy business names
- Fix machine offline status display - now correctly shows online machines
- Add humanize_datetime utility function for better timestamp display

All machines now correctly display:
- Online status (matching actual Headscale status)
- Technical username (myuser)
- Actual pharmacy name (세종온누리약국)
- Manager name and business details
