Live button-driven scanning with EEPROM calibration

- ScanSession: scan-mode context manager with bright-pixel auto-exposure and
  sensor colour gains; tools/scan.py scans on the scan button with live stitching
- Read-only EEPROM access and calib.py parser (laser geometry, intrinsics,
  colour gains, black/white flat-field samples); flat-field correction in Stitcher
- OV7740 sensor access via the MCU proxy; colour gains from EEPROM fix green cast
- Stitcher: colour support, high-passed registration (robust on blank paper)
- RE notes on the Mac app's colour, exposure, stitching and button handling
