Yes/No Screen: Allow accept to be button release

Allows the ACTION_YESNO_ACCEPT action to be set
to a button release by ignoring certain system events.

Moving USB init in main.c to the last thing to prevent
getting stuck in the USB prompt, if enabled.
Also changing ACTION_YESNO_ACCEPT to button release on erosq
