v0.328.0: the catalog allow-list — the box refuses container rights a template asks for and the box does not give (R-971, D2 = A)

internal/privpolicy checks the RENDERED compose (privileged, cap_add, devices, host namespaces, security_opt,
sysctls, volumes_from, build/include/extends, env_file/config files outside the stack dir, aliasing named volumes,
binds outside the box's data roots, the Docker socket, propagation, ${VAR} in a privileged key) against an
allow-list compiled into the controller (one entry: homepage's read-only socket). Asked before every compose
write: the 15-minute sync, the guarded update/ladder step, the install, both settings changes, both restores
(before the stop). A refusal writes nothing, keeps the app on its last good compose, raises the operator-only
event app_definition_refused once per definition and puts one line on the app page. The sync never copies a
template named like a controller infra stack. Structural guard TestAllowList_IsWiredIntoEveryComposeWriter.
