feat(wallpapers): add Immich integration with caching and rotation

This patch adds Immich integration for remote images with local
caching and pruning.
It adds image rotation to the crop flow and stores rotation
with the crop state.
It adds progress tracking and size checks during image
download to avoid oversized assets.

- Add Immich caching with size limits and automatic pruning
- Extend crop handling to support rotation and persist it
- Improve download progress and error messaging
