fix(modal): accept-by-known-id keeps the raw suggestion row identity for the drop

Spreading canonical_tag_id onto a raw suggestion changed its _keyOf
identity, so _dropEverywhere missed the actual list row and the panel
kept showing an already-accepted suggestion. Pass the resolved id as an
option instead; pinned with a raw-suggestion spec.
