Add SettingsTab, StatusTab, DataTab and wire up DeviceController
- SettingsTab: chamber ID, master CSV mapping, wafer behavior toggle,
light/dark mode toggle, Edit CSV Metadata dialog
- StatusTab: connection status, wafer info, activity log (blank until
Detect Wafer fires)
- DataTab: empty state, ready for parsed data
- HomePage: side rail buttons dispatch device actions and jump to Status
tab; selectedSideActionIndex defaults to -1 (nothing active on startup)
- DeviceController registered as QML context property in main.py
- LocalSettings: added status persistence fields
- Theme: added subheadingColor and disabledText
- Added serialcomm/ package and backend data/graph modules
- gitignore: added build/, dist/, *.spec
