MUL-5258: feat(issues): show agent-working indicator in Table view (#5875)

* feat(issues): show agent-working indicator in Table view

Reuse the self-contained IssueAgentActivityIndicator (already in List and
Board views) in the Table view's Issue column, rendered right after the
identifier and before the title — matching the List view placement so the
'agent working' cue sits in the same spot across all three views. The
indicator returns null when no agent is active, so inactive rows are
unchanged.

* test(issues): cover Table agent-working badge insertion

The previous stub returned null with no assertion, so deleting the badge
insertion in table-view.tsx would still pass every test here. Render a
marker carrying the issue id and assert the Table cell mounts it for the
row's issue, positioned between the identifier and the title (identifier →
activity → title, matching List/Board). Verified the new test fails when the
insertion is removed.
