Subject: [PATCH] fix(cli): use PDS-returned blob mimeType after upload

Local mimeType from filename extension can disagree with the stored blob
when PDS dedupes (same CID, original mimeType wins). Record then
references the blob with wrong mimeType and PDS rejects publish. Trust
uploadBlob response for mimeType and size.
