The control bridge sent a command, slept 0.3 s and read /tmp/warden-ui.dbg,
so a page that took longer to build handed the host the previous command's
reply as if it were this one (flare-edge #152). It now removes the old
reply before sending and waits, up to 5 s, for warden-ui to rename the new
one into place, the same recipe tools/warden-ctl and flow-run-hw.sh use.
