learn: surface logo fingerprint + flag rejected logos (overnight cycle 4)

Each /learn card now shows how the VLM read that vendor's reference logo — a green
'🏷 reads X · typeface' for validated logos, and a red '⚠ logo rejected — read as X'
for the 6 logos the validation pass dropped (Versace→Savannah, Hollywood→Hollywood
Reporter, Mid Century→20th Century Fox, etc.) so Steve can review the misfires at a
glance. Reads logo_valid/logo_reads already in /api/vendor-profiles. $0 (local).
