fix(journey): resilient per-file photo upload with retry and progress

Replace the single combined-FormData POST (which timed out at 8 s on slow
connections) with a concurrent per-file upload queue: each file is uploaded
individually with timeout disabled, up to 2 retries with backoff (4xx errors
are not retried), and a stable idempotency key per file so server-side dedup
prevents duplicates on retry. Partial success is preserved — succeeded photos
merge into state immediately; failed files stay queued for re-save. Progress
is surfaced as "Uploading n/N" in both the entry editor and gallery upload
button. Adds translations for two new keys across all 15 locales.

Closes #1013
