/**
 * RBAC guards on the DANGEROUS fleet + host-terminal + domain/TLS actions. The RBAC foundation
 * (Role enum, Gates manage-fleet/manage-panel + operate) is committed separately; this proves the
 * abort_unless(...) guards fire at every dangerous entry point:
 *  - manage-fleet gates server registration + credential surface (CreateServer, credential
 *    delete/toggle, SSH-key install, host-terminal login) and the HOST shell target;
 *  - operate gates a SERVER terminal session (day-to-day), not the host shell;
 *  - manage-panel gates the domain/TLS control-plane mutations (System\Index).
 * Admin (factory default) may act; operator/viewer are refused with 403 where they lack the
 * ability. Every host/SSH service is mocked so no real network is touched (hermetic RefreshDatabase).
