* fix: office mime types

* fix(s3): upload MIME validation, multer whitelist, API error status

- Treat AVI/MPEG mime aliases (incl. video/mp1s vs video/mpeg) as matching
- Optional allowedExtensions on multer for dataset images and localFile
- Map S3/business errors to 4xx in jsonRes where appropriate
- Align presign max size with team plan; fix dataset import size UX
- Add upload validation tests

Made-with: Cursor

* fix: show clear message when upload frequency limit is exceeded

- Reject ERROR_ENUM.uploadFileIntervalLimit from authFrequencyLimit instead of Mongo doc

* fix file token validation and upload mime checks

* fix: test

* fix(s3): treat m4a audio/mp4 and audio/x-m4a as equivalent

- Add MIME equivalence group for AAC/M4A container mismatch (mime-types vs file-type)
- Add upload validation test for minimal ftyp/M4A buffer
- Test env: keep FILE_TOKEN_KEY in vitest test.env and test/setup.ts (drop loadTestEnv file)
