fix: evaluate automation schedules on Windows with PostgreSQL (#30424)
Since 0.11.4, creating or editing an automation on Windows with PostgreSQL fails with a 400, and the scheduler logs NotImplementedError on every tick, so automations do not work at all on that setup.

Schedules are now evaluated in a worker subprocess so a pathological rule can be killed after the 2s budget. On Windows with PostgreSQL, Open WebUI switches to the selector event loop that psycopg needs, and that loop cannot spawn subprocesses.

When spawning fails there, the evaluation now reruns on a Proactor event loop in a worker thread. The subprocess, the 2s budget and the kill on timeout all stay the same, and the global loop policy psycopg depends on is untouched. Falling back to a plain thread was considered and rejected: a thread cannot be stopped, so a costly rule would keep burning CPU after the timeout.

Verified with a loop that refuses subprocesses: base raises NotImplementedError, the fix returns the same results as base, still times out a pathological rule at 2s with the worker killed, and leaves no processes or loops behind under repeated and concurrent calls. Other platforms take the unchanged path.

Fixes #30400
