Record DEC22: a bound patient login reaches its own patient-namespace wallet

Answered by the user on 16 October while closing the DEC19 slice: the wallet
gate DEC19 was waiting on has a decision. A live patient_user_links binding
gates walletForPatient() for a patient-role login, exactly as it gates the
portal; the user-namespace wallet is unchanged; an unbound login reaches
nothing. Not yet implemented - the gate is the next slice, and CONTINUE.md
points at it.
