Implemented cache-busting mechanism to prevent stale avatar images
after upload. React Native Image component caches images by URI,
causing old avatars to persist even after successful upload.
Changes:
- Added bustImageCache() utility function in utils/imageUtils.ts
- Appends timestamp query parameter (?t=timestamp) to avatar URLs
- Skips cache-busting for local file://, data: URIs and placeholders
- Applied bustImageCache() to all avatar Image components:
- Beneficiary detail screen (header, edit modal, lightbox)
- Beneficiary list cards on dashboard
- Ensured loadBeneficiary() is called after avatar upload completes
- Added comprehensive unit tests for cache-busting logic
Backend already generates unique URLs with timestamps when uploading
to MinIO, but this ensures frontend always requests fresh images.
