Stop tracking deployment status in the Hosts table

Same problem as the deployedTargets removal, just in markdown instead of
Nix: which variant of a buildtype is actually deployed is live
infrastructure state, and a committed table can't stay accurate as that
changes -- it already required a manual edit on every migration and had
drifted before. Keep only what doesn't rot: what each target is for, and
stable naming history. Point at the live node / /etc/flake-target instead
for actual deployment status.
