MJ: User Settings key for the per-user "record this voice call" consent toggle. Stored as
the literal string 'true'/'false' (read with === 'true'), cross-device via
UserInfoEngine. The pre-call picker writes it; the session service reads it as the
default when the caller doesn't pass an explicit consent value.
