feat(modal): green ✓ / red ✗ verdict pair on suggestion rows

Replace the single "Accept" pill in the modal Suggestions rail with the
eval card's green ✓ / red ✗ language: ✓ accepts the tag (positive), ✗
dismisses it for this image — which already persists a TagSuggestionRejection
(hard negative the heads train on). The pair occupies ~the footprint of the
old pill, so per-image rejection becomes a one-click peer of accepting
instead of being buried in the kebab.

Dismiss moves off the 3-dot menu, so the kebab now only carries alias
actions and is hidden when none apply (centroid hits with no alias option).

Toward #1134 (native per-image negatives in the rail). The bigger piece —
heads as a suggestion source feeding this panel — is still ahead.
