fix: convert ucsid, driver-params to oneshot_async; add ipcd/ptyd overrides

Config changes to prevent scheduler hangs on live-mini ISO:
- 00_ucsid.service: scheme -> oneshot_async
- 13_driver-params.service: scheme -> oneshot_async
- 00_ipcd.service: new override (notify -> oneshot_async)
- 00_ptyd.service: new override (notify -> oneshot_async)
- 00_pcid-spawner.service: new override (oneshot -> oneshot_async)
- base: update submodule to 4bfb878 (force-run scheduler)
