- New attachments table (FK to receipts), dual-write: file on disk + DB blob.
- On-disk layout split: receipts under <ROOT>/receipts/<YYYY>/..., attachments
under <ROOT>/attachments/<YYYY>/..., attachments named from the parent
receipt's date+amount stem (_att, _att_1, ...).
- Upload form gains an optional multi-file "Additional files" field; the files
ride along with POST /upload, saved after the receipt row exists. No AI runs
on attachments; primary-image auto-fill unchanged.
- GET /attachment/{id}/file serves blobs; confirm page lists them; recent list
links them. Adding attachments to an already-saved receipt is not yet supported.
