Nic BoetandClaude Opus 5.5 99cf213f62 fix: forward control requests to the server that records the monitor 
In a multi-server setup a PTZ move, preset or light command sent to one
server for a monitor that another server records never reached the
camera. Monitor::sendControlCommand() passed the zmcontrol option string
to the other server's monitors/daemonControl API, which only starts and
stops zmcontrol.pl, so the request built a URL like
daemonControl/4/ --panspeed=51 ... --command=moveConLeft/zmcontrol.pl.json
and answered "Failed". The web UI's own PTZ buttons send to the
monitor's server and were not affected; clients that send every request
to the server they log in to (zm-py, pyzmNg, zmNinjaNg, aiozoneminder)
and monitor actions whose target is on another server were.

ajax/control.php now hands such a request, as received, to the index.php
of the server that records the monitor (or the action's target), with
the auth relay in place of the caller's credentials, and answers with
that server's reply. That server checks the permissions and builds the
command itself. A request is forwarded at most once.
