Refactor photo upload pipeline

Implement comprehensive error recovery mechanisms for the photo upload pipeline in `UppyPhotoSubmissionUpload.tsx`. This includes adding exponential backoff to retries, graceful degradation for partial uploads, and cleanup for orphaned Cloudflare images. The changes also enhance error tracking and user feedback for failed uploads.
