- Remove dead kitchen->KDS internal API (api/internal.py, verify_internal_secret)
— KDS reads kitchen_db directly (E16), nothing ever called this endpoint
- Add expires_at to dispute_attachments; public attachment links now expire
after 30 days instead of staying valid forever (A4)
- Add services/upload_validation.py: sniff real file content via python-magic
instead of trusting the client-supplied Content-Type header, plus a 20MB
cap. Applied across invoices/logbook/food_flags/credit_notes/disputes
upload endpoints (A5) — disputes previously had no file-type check at all
- Fix nginx client_max_body_size drift (800m -> the plan's intended 20m)
