Add pf visibility and a wg-quick watcher check, add a neutral row status

checks/pf.sh reports pf enabled/disabled, state table usage (warn/down
as it nears the configured limit), and the loaded filter/nat rule
count, then lists each active rule as its own row for at-a-glance
visibility into what's actually being enforced.

Those rule rows use a new "info" status (gray square) rather than
"ok" - they're not a health check on any individual rule, so a green
square there would misleadingly imply otherwise. render.sh maps
info -> gray; anything else still falls back to red.

checks/wg-watcher.sh checks the route-monitor process wg-quick spawns
to react to WAN interface/address changes - it isn't rc.d-managed, so
there's no `service status` for it, hence the new proc_running helper
in lib/common.sh (pgrep -f based).
