Fix IDS uEye AOI issue with non-zero Y offset

Browse Source 
- Re-validate AOI configuration before starting video capture
- Fixes 'Invalid buffer size' error when using Start Y > 0
- Query current AOI and re-set it to force SDK internal state update
- Tested with Start Y=0 and Start Y=500 - both work correctly
