Folds all three follow-up items tracked in #525 into one commit:
1. Mirror PR #500's category scoping on adminPhotos.js. The admin
upload route at adminPhotos.js:231 still accepted any category_id
without event scoping — quietly less strict than the public v1
API after #500 landed. Same one-liner fix (event_id OR is_global)
with a matching 400 response shape so admin + v1 stay consistent.
2. Extract a shared slugify() in backend/src/utils/slug.js with the
NFD-strip-combining-marks fix from #502, and route 5 callers
through it:
- adminEvents.js (event-name slug)
- events.js (event-create slug)
- v1/events.js (replaces local slugify helper)
- adminArchives.js (archive→category slug)
For pure-ASCII input the output is byte-identical to each old
inline pipeline, so existing slugs in the DB keep round-tripping
cleanly via lookup. Accented inputs now transliterate (Família
→ familia) instead of dropping the diacritic (Família → f-mlia).
adminCategories.js stays with its own pipeline (underscores-as-
word-chars semantics differ from the events-style transform —
changing would silently shift wedding_party → wedding-party on
new inserts). xmpGenerator.sanitizeKeyword stays unchanged for
the same compat-cautious reason.
3. Cover the v1 upload happy path. Existing test only exercised the
400-out-of-scope branch. Add two happy-path cases that stub
sharp / generateThumbnail / storage.putFromFile and pin the
response shape (id, category_id, type, etc.) plus the collage-
slug → type='collage' flip. Temp file recreated in beforeEach
because the handler unlinks it on success.
Tests:
- New slug.test.js: 22 cases pinning ASCII parity with the legacy
pipeline (so the refactor is provably non-breaking for existing
data) and the corrected accent handling across de/es/fr/nl/pt
inputs, plus CJK and edge-case behaviour.
- events.category.test.js: 4 tests total (2 existing + 2 new happy
path).
- galleryOgService.shareImage.test.js: 11 (3 added in #521 + 8 pre-
existing) still pass.
37 tests pass across the three touched files.
