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
