Clear out user.id except for sending to phone (#8202)

Browse Source 
* Null out user.id except for sending to phone

* Fix

* Update src/modules/NodeInfoModule.cpp

Co-authored-by: Copilot <175728472+Copilot@users.noreply.github.com>

* Copilot garbage

* This is unnecessary, because we don't stored user.id on userlite

* Don't need this

* Fix warning

* Just alter the protobuf

* Alter protobuf doesn't do anything with the altered data, so let's re-encode it

* Check inputbroker before access
