fix: wire through silent restart clear resume state with sdk (#2033)

## Summary

After a silent reboot, there was a small window where the esp32 would
listen for button presses but the full refresh would hold the event
loop. This gave a UX experience where the silent reboot had completed to
the home screen, a user taps select (at any time during the process),
and they find themselves unexpectedly in a book.

## Additional Context

This must land after
https://github.com/crosspoint-reader/community-sdk/pull/11 and will need
the submodule SHA changes included in.
