The security hardening (NoNewPrivileges, RestrictAddressFamilies,
MemoryDenyWriteExecute, RestrictRealtime, ProtectSystem=strict) all
blocked podman container management via sudo. These are temporarily
disabled until TASK-11 (rootless podman migration) is complete.
Remaining active protections: ProtectSystem=true (/usr, /boot),
ProtectHome=yes, PrivateTmp=yes, PrivateDevices=no (mesh radio).
Also adds TASK-11 to MASTER_PLAN.md for tracking the rootless podman
migration that will allow re-enabling full security hardening.
