ulfius: client_address carries the whole peer sockaddr; forgectrl.auth asserts the loopback report is accepted

Browse Source 
The dual-stack listener reports every peer as a sockaddr_in6; ulfius
2.7.15 copied sixteen bytes of it, so forgectrl's loopback-only cooling
channel refused the controller's every report (403 loopback only) and
the engine never saw a run or an armed window. The recipe carries the
patch: a sockaddr_storage allocation and a copy of the family's length,
in the dispatcher and in ulfius_copy_request.

forgetest: forgectrl.auth asserts POST /cool/state from loopback -> 200
beside the LAN 403, and covers src/peer.*. BRINGUP item 21 and the
campaign log record how the campaign on dev 20260824215906 found it.
