Cannot Resume a Running Backtest After Closing the Browser Tab

Issue
When I start a back-test and accidentally close or refresh the browser, the running job disappears and cannot be resumed.

Expected
The original back-test should still be visible so I can monitor its status or view results once finished.

Actual
The running job is no longer listed. I must start a new back-test instead.

Impact
Must keep the tab open the whole time; risk of losing progress if the tab closes.

Suggested Fix
Persist running back-tests on the server and show them in the UI so users can reconnect after a page reload.
