Add a "Max parallel executions" setting to the General settings tab so
the queue can run more than one task concurrently. QueueService now
tracks multiple active slots and reads the limit from app settings each
cycle, so changes take effect without restarting the worker.

Also fixes WorkerHub.UpdateAppSettings falling back to "bypassPermissions"
when AppSettingsEntity and the runtime default are "auto". The fallback
now matches the entity default.
Replaces three scattered model lists (ListSettingsModalViewModel,
DetailsIslandViewModel, GeneralSettingsTabViewModel) and the hardcoded
planning model with a single source. Planning launcher now uses the
opus alias instead of pinning claude-opus-4-7.
