feat: Complete ApsGo hydroponics system with multiple features

Features implemented:
- Dashboard with real-time sensor monitoring (temp, humidity, light, soil moisture)
- Water flow status indicator with color coding
- Time-based scheduling (Kontrol Waktu/Jadwal)
- Sensor-based threshold control (Kontrol Sensor/Threshold)
- Smart mode with auto-stop when target reached
- Three pump controls: Air, Larutan Nutrisi, Pengaduk
- Manual control for all actuators
- History/logging system
- Firebase Realtime Database integration
- Railway worker backend service

UI/UX improvements:
- Material Design 3 components
- Badge indicators for active pumps
- Conditional rendering (show only when active)
- Responsive layouts with Wrap widgets
- Color-coded status indicators

Backend fixes:
- Fixed water_flow reading from Firebase
- Fixed threshold model copyWith method
- Added pompa_pengaduk support across all models
- Smart mode with per-pot independent monitoring
- Cooldown per-threshold (not per-pot)
- Valves stop together when targets reached

Renamed: All 'Pupuk' references to 'Larutan Nutrisi Cair'
