refactor(installer): move plymouth fully into optional apps

Both plymouth and plymouth-custom are now optional — neither is strictly
required, so removing plymouth from the core COMPONENTS checklist and
treating it identically to plymouth-custom.

- Remove plymouth from COMPONENTS checklist, counter, summary, and dispatch
- Add plymouth back to modules.conf (default=on, excludes=plymouth-custom)
- Regenerate all sentinel regions; plymouth now appears in optional apps
  checklist/summary/conflicts/dispatch alongside plymouth-custom
