D10 closed the client-facing leak; this completes the defense-in-depth
so a generic-adapter connection's custom auth-param value is also
scrubbed from the operator-readable door_access_log / callDoor reason
regardless of param name. auth_param added to ConnRow +
loadEnabledConnection + the test/selfEntry selects; threaded into every
callDoor (which already redacts reason/snippet by it) and auditDoor
gained an optional authParam. Native HeatSync (e=) was already covered;
this hardens custom generic adapters. 532 tests.
