fix: correct exposure units from seconds to milliseconds

Browse Source 
- Update idsueyesrc exposure property to use milliseconds (per gst-inspect)
- Fix default exposure value from 0.016 to 10ms
- Update validation range to 1.0-1000.0ms in control server
- Correct all documentation and examples in UDP_CONTROL_PROTOCOL.md
- Update test_exposure_control.py to use millisecond values

Resolves unit mismatch between documented seconds and actual milliseconds
expected by the idsueyesrc GStreamer element.

# Features:
# - Video streaming on UDP port 5000 (127.0.0.1)
# - Control interface on UDP port 5001 (0.0.0.0)
# - Dynamic exposure control (0.001-1.0 seconds)
# - Dynamic exposure control (1.0-1000.0 milliseconds)
# - Dynamic framerate control (1-500 fps)
#
# Control Commands:
# SET_EXPOSURE <value> - Set exposure in seconds (e.g., 0.016)
# SET_EXPOSURE <value> - Set exposure in milliseconds (e.g., 16)
# GET_EXPOSURE - Get current exposure value
# SET_FRAMERATE <value> - Set framerate in Hz (e.g., 30)
# GET_FRAMERATE - Get current framerate
# STATUS - Get pipeline status and current settings
#
# Example Usage:
# echo "SET_EXPOSURE 0.010" | nc -u 127.0.0.1 5001
# echo "SET_EXPOSURE 10" | nc -u 127.0.0.1 5001
# echo "GET_EXPOSURE" | nc -u 127.0.0.1 5001
