fix(modal): kebab menus weren't opening (chip + suggestion rows)

Operator-flagged 2026-06-02. Both kebab activators were broken:

- TagPanel chip kebab had `@click.stop` directly on the v-icon
  activator. In Vue 3, an explicit @click on the same element as
  `v-bind="props"` overrides the spread onClick — so Vuetify's
  activator handler never fired. Menu never opened.

- SuggestionItem kebab didn't have @click.stop, but for consistency
  and to make both kebabs follow the same shape, wrap it too.

The fix: each kebab is now wrapped in a `<span @click.stop>`. The
v-icon / v-btn receives Vuetify's onClick cleanly and opens the menu;
the bubbling click then reaches the span where stopPropagation
absorbs it before it can affect a parent (the v-chip's close button
in TagPanel's case).
