[Eval > Test Suites] Stop confirmation modal allows double-submit, causing Conflict error toast

[mikhailcauseloue]

EPAM AI DIAL Admin version

Admin: [FE]0.21.0-dev.148 [BE]0.21.0-dev.10

How to reproduce

1. Login to Admin.
2. Open any Test Suite that has a run with Running status, go to the Runs tab.
3. Click the context menu (⋮) on the running run row → Stop.
4. In the Stop confirmation modal, click the "Stop" button twice in quick succession (fast double-click, before any visual reaction from the UI).

Actual result

Two stop requests are sent. The first succeeds and the run is cancelled. The second request fails with a 409 Conflict because the run is already in CANCELLED status. The user sees both a "Run stopped" success toast and a "Conflict — Cannot cancel run with status: CANCELLED" error toast.

Expected result

Only one stop request is sent. The button should be disabled or the modal should close immediately after the first click, preventing the duplicate request.
