* fix(server): compare integrity paths independently of unicode normalization
The untracked-file check compared on-disk paths against the database
byte for byte. macOS writes decomposed (NFD) filenames while an upload
stores the composed (NFC) form, so every asset with a non-ASCII name
came back from getAssetPathsByPaths under a different byte sequence,
was never removed from the candidate set, and was reported as an
untracked file. One reporter saw 14k false positives on a 55k library.
Look the batch up under both normal forms and key the comparison on
NFC, so a path that differs only in normalization is recognised as
tracked.
* test(server): cover normalized integrity lookup
