feat(modal): surface ML suggestions inline in the tag autocomplete

The image's Camie suggestions now appear in the tag input's dropdown as you
type, filtered to the query and de-duped against the server autocomplete hits,
so the operator can pick a suggestion without hunting for it in the Suggestions
panel below (operator-asked 2026-06-07).

- Unified `rows` model (hits → matching suggestions → create row) so the
  highlight index maps 1:1 to a row across all three sections; arrow/Enter/Tab
  drive the whole list.
- Suggestion rows are marked (accent left-border + mdi-auto-fix score chip) and
  show a "new" hint when the suggestion would create a tag.
- Picking a suggestion emits accept-suggestion → TagPanel runs the SAME accept
  path as the Suggestions panel (creates raw tags, records acceptance, drops it
  from the panel), then refreshes the chip rail.
