fix(ui): use pointer cursor on workflow execution rows

[57hemanth]

What

Each row in the workflow executions list (/workflows/{id}/executions) is a
clickable Link that navigates to the execution detail, but the row class
hardcoded hover:cursor-default. As a result, hovering over a run gave no
cursor affordance that the row is interactive.

This switches the row to hover:cursor-pointer to match its click behavior.
The nested terminate (✕) icon keeps its own hover:cursor-pointer, and status
icons are unaffected.

Why

Consistency and discoverability: the entire row is clickable, so it should show
the pointer cursor like every other interactive navigation target in the app.

Changes

• frontend/src/components/executions/nav.tsx: hover:cursor-default →
  hover:cursor-pointer on the execution row link.

Testing

CSS-only class change with no logic impact. Refresh the executions page and
confirm hovering a run shows the pointer cursor, the row still navigates to the
execution detail, and the terminate icon on running executions is unaffected.

Before

After

---

Summary by cubic

Use a pointer cursor on workflow execution rows so users see they are clickable. Replaced hover:cursor-default with hover:cursor-pointer on the row link in frontend/src/components/executions/nav.tsx; terminate and status icons are unchanged.
