ProxyTimeout cannot be set inside <Location>. Express the per-route
timeout via the timeout= parameter on ProxyPass instead, matching the
ppt-tool pattern in the optical-dev vhost.
Match the convention used by every other app on optical-{dev,prod}:
each app ships one /opt/<app>/deploy/<app>.conf, and the per-host
vhost adds a single `Include` line.
Combines apache-dev.conf and apache-prod.conf (which were identical)
into apache-hm-aiqc.conf. Drops X-Forwarded-Proto and ProxyPreserveHost
since the parent vhost already sets them globally. Raises the body
size to 500MB inside /hm-aiqc/ for video uploads.
