/api/system/info reported the Proxmox host's 16GB (the controller container
reads host /proc/meminfo with no lxcfs), defeating the deploy memory-headroom
hard-block (deploy.go uses GetMemoryMB). readMemInfo now prefers the cgroup
memory limit (v2 memory.max / v1 memory.limit_in_bytes; sentinels = unlimited)
when finite and below the host total; used = memory.current/usage_in_bytes.
Test info_cgroup_test.go (cgroup v2 cap wins, v2 max sentinel, v1 unlimited,
v1 finite) — fails on pre-fix code.
