Lock activity to portrait; drop all camera-image rotation tracking

Browse source 
Stop trying to rotate the camera image based on device orientation.
The activity is now locked to portrait (screenOrientation="portrait"),
so the GL surface stays portrait-sized regardless of how the device
is held, and the camera passthrough goes back to the simple
texCoordsBack 90° rotation that was working before any of the
v1.1.6–1.1.13 attempts at landscape support.

Net effect: the camera image stays in the device's portrait frame
and visually follows the phone as it tilts (since there is no
inverse rotation cancelling it). The UI is also locked to the
portrait layout for now — a follow-up will add Modifier.graphicsLayer
rotations to the icon overlays so they stay readable when the phone
is held sideways. screenOrientation switched from fullSensor to
portrait; the rest of the file changes are reverts of the orientation
plumbing introduced in v1.1.6 and its follow-ups.

Bump to 1.1.14.
