test(post-form): assert 1–6 photo rule

Add a test for the ≥1-photo requirement (submit blocked with a photo-section
error) and the max of 6 (FilePond maxFiles). Rework AE4: a corrupt HEIC is the
only "photo", so fail-closed now means submit is blocked rather than posting a
text-only entry. Give the success-CTA test a photo so it can post under the new
rule.
