Uploading N files fired N sequential XHRs (one POST per file). Select-many now
goes up in a single request.
- Server POST /api/content: upload.array-style `files` field (up to 20) via
upload.fields, looping ingestUploadedFile per file. Keeps the legacy single
`file` field so older clients / API callers are unaffected. Response shape is
backward-compatible: a single file returns the content object (what every
existing caller reads), a batch returns the array.
- api.uploadContent: accepts a File, FileList, or array; appends all under
`files`; aggregate upload progress; resolves to object (single) or array
(batch).
- content-library handleFiles: one batched request with aggregate progress and
a "N files uploaded" toast instead of a per-file loop.
- en/es i18n for the count-based progress/toast strings.
checkStorageLimit is left as-is — it's a coarse pre-gate (blocks only when
already at/over the limit), same as before; per-file aggregate sizing was a
listed "consideration", not required, and is out of scope here.
Test: content-multi-upload.test.js drives the real router+multer over HTTP —
3-file batch creates 3 rows and returns an array, legacy single `file` returns
an object, single `files` returns an object, empty -> 400. Suite 545/545.
