iOS Safari kills fetch requests when the app goes to background or
the connection drops during large uploads, producing 'load failed'.
The sync engine was burning through all 5 retries instantly with no
delay, so a transient failure became permanent.
Changes:
- Add AbortController timeout (120s) on upload fetch
- Add exponential backoff between retries (2s, 5s, 10s...60s)
- Increase max retries from 5 to 15 for flaky mobile networks
- Remove 10MB resize step that was re-compressing photos already
sized at capture time, avoiding extra memory pressure on iOS
- Log photo size with each upload attempt for easier debugging

After renaming a file, loadDirectory() was called which rebuilt the
galleryImages array in new alphabetical order. The gallery index
didn't change, so it now pointed to a different file — subsequent
renames hit the wrong file.
Fix: only update local state during the gallery session, defer the
file list refresh to when the gallery closes.
