test(jetbrains): stabilize workspace reload lifecycle

[markijbema]

What changed

Make KiloBackendWorkspaceTest wait for its coroutine scope to finish during teardown and close the mock server before joining so blocked requests are released. The global.disposed test now subscribes before sending the SSE event, waits for the next Ready state instead of accepting the existing one after an arbitrary delay, and verifies that reload replaced the cached workspace.

Why

The failed job timed out while setting up this test after the preceding concurrent-reload test. Teardown cancelled asynchronous work without joining it, allowing request and watcher jobs to outlive their test fixture. The disposed-event assertion also treated the pre-event Ready state as proof that reload finished. Causal event synchronization and complete fixture cleanup remove both races without extending normal test waits.
