feat(post-form): photos-first order, auto-collapsing photo summary, success-only view

- Reorder blueprint to Photos → Title → Content; drop title autofocus so the
  picker leads (it anchors what you write).
- After upload the photo section auto-collapses to a live summary bar
  ("✓ N photos ready — tap to review") and re-expands on tap; the field's
  own .form-label is hidden so the <summary> is the sole header. Trailing
  refreshes settle the summary past FilePond's event/DOM timing gap.
- Replace FilePond's murky completed-thumbnail overlay with a clean green ✓
  badge (remove action left intact).
- On a successful post, hide the reset form + location/weather controls so
  only the "✓ Saved" confirmation + View-journal CTA remain.
