Gallery imports now show the effect live as you adjust parameters,
matching the camera preview experience. Uses a downscaled (1024px)
source bitmap for fast recomputation via collectLatest, which
cancels stale frames when params change mid-computation.

Gallery imports already have the original on-device, so only save
the tilt-shift processed version. Camera captures continue saving
both versions since the original only exists in memory.

- Replace unsafe as Any / as SaveResult casts with a sealed
CaptureOutcome class for type-safe continuation handling
- Catch SecurityException separately with permission-specific messages
- Replace raw e.message with generic user-friendly error strings
- Add inJustDecodeBounds pre-check in loadBitmapFromUri to downsample
images exceeding 4096px, preventing OOM from huge gallery images

Instead of immediately processing gallery images, show a preview where
users can adjust blur parameters before committing. Adds Cancel/Apply
buttons and hides camera-only controls during gallery preview mode.

- Increase bottom padding and add systemGestureExclusion to prevent
accidental navigation gestures from the capture controls
- Save both original and processed images with shared timestamps
(TILTSHIFT_* and ORIGINAL_*) via new saveBitmapPair() pipeline
- Show animated thumbnail of last captured photo at bottom-right;
tap opens the image in the default photo viewer
- Add gallery picker button to process existing photos through the
tilt-shift pipeline with full EXIF rotation support

Track the current bitmap through the decode→rotate→effect pipeline
with a nullable variable. On exception, the in-flight bitmap is
recycled in the catch block to prevent native memory leaks. Errors
are now logged with Log.e and a proper companion TAG.

Track all intermediate bitmaps with nullable variables and recycle
them in a finally block. This prevents native memory leaks when an
OOM or other exception occurs mid-processing. Variables are set to
null after recycle or handoff to the caller.

runBlocking on the camera callback thread could deadlock when
saveBitmap() needed the main thread. Split capturePhoto() into two
phases: synchronous CPU work (decode/rotate/effect) inside the
suspendCancellableCoroutine callback, and suspend-safe saveBitmap()
after the continuation resumes in coroutine context.

2D positioning:
- Add positionX parameter to BlurParameters (was only Y before)
- Update shader with uPositionX and uPositionY uniforms
- Single-finger drag now moves focus center anywhere on screen
- Update gradient mask generation for capture
Rotation tracking:
- Remove dampening from rotation gesture (1:1 tracking)
- Rotate gesture now directly tracks finger movement
- Preview effect rotates in sync with overlay
Overlay and shader sync:
- Both now use same positionX, positionY, angle parameters
- Preview blur effect matches overlay visualization
