 *  1) Schema + folder + perms
 *  2) Model: upload rejects empty files, bad MIME, oversize
 *  3) Model: valid upload lands on disk + creates DB row + roundtrips list/find
 *  4) Model: remove soft-deletes DB row + removes file from disk
 *  5) Kind + label defaults sane; bad kind falls back to OTHER
 *  6) Perms granted to whoever has saveSubmissionAj
 *  7) Controller endpoints exist
 *  8) View surface: proof-of-submission section + upload modal + kind chips
 *  9) Storage path is under uploads/tenders/{tid}/submissions/
 * 10) MIME whitelist covers PDF / JPG / PNG / DOCX / XLSX / ZIP / TXT
