refine: improve exposure control precision and validation

- Lower minimum exposure from 1.0ms to 0.015ms in launch-ids.py validation
- Add exposure range validation (0.015-30000ms) to camera_control.py
- Update help text to display exposure range for better user guidance
- Adjust camera config: swap binning/subsampling values in nightcolor preset
- Add comment explaining subsampling vs binning behavior

Enhances exposure control granularity and provides clearer validation
feedback while optimizing camera configuration for low-light scenarios.
