Revert "daemon: increase memory resource"

This reverts commit 7c5e31c.

The memory bump to 512Mi is no longer needed: bootc switch now runs
as a transient systemd unit on the host (outside the pod cgroup), so
its memory usage does not count against the daemon pod limit. 128Mi
is sufficient for the daemon itself (Go binary, controller-runtime,
API watches).
