camera: pin macOS photo connection to .portrait (counter-intuitive)

Browse Source 
`.landscapeRight` / `videoRotationAngle = 0` both still produced a
JPEG rotated 90° CW on macOS. User verified that `.portrait` /
`videoRotationAngle = 90` is the value that DOES NOT rotate the
captured frame on the photo output's connection — counter to the
iOS convention where `.portrait` rotates the landscape sensor
frame into portrait pixels.

I'd expect this to be macOS-specific photo-pipeline plumbing; the
data output's connection still doesn't honor the setter (isSupported
returns false or the setter no-ops), so preview + video stay
unaffected. Verified empirically; not chasing the AVFoundation
source for the why.
