Add uIsFrontCamera uniform to shader and adjust coordinate
transformations for front camera's mirrored texture coordinates:
- Position transform: (1-posY, 1-posX) instead of (posY, 1-posX)
- Angle transform: -angle - 90° instead of +angle + 90°
Applied to linearFocusDistance, radialFocusDistance, and blur
direction calculations in sampleBlurred.

- Add separate texture coordinates for front and back cameras
- Front camera uses mirrored coordinates for natural selfie view
- Add setFrontCamera() method to renderer for dynamic switching
- Update texture coord buffer on GL thread when camera changes
- CameraScreen observes isFrontCamera state to trigger updates
