Hacks are ok with web and app deployments where you are able to patch and fix to your heart's content and the damage is not life threatening.
I have worked with the medical industry, the amount of formal validation and verification that goes through on software is insane compared to what we have in the "move fast and break things" world.
Even if it is "temporary" and "desperate" I would stay away from this mentality as much as humanly possible.
Use the language your team is familiar with! If it is PHP don't hesitate just because it is not "cool"..
PHP was a great tool back in the day and today!
PHP with a decent framework like Laravel [1] or Zend Framework [2] really works well and addresses all the features that you have listed (except the last 2).
Uniquely among modern languages, * PHP was born in a web server *. Its strengths are tightly coupled to the context of request-oriented, server-side execution.
We've managed to develop several complex apps over the last 10 years on PHP. For Web Socket support, we use Socket.IO or Firebase and it both really well together with PHP.
If you choose PHP now, you are not alone. Many companies still choose PHP for their Web Application. Slack uses PHP for most of its server-side application logic [3]
I wrote an HTML file in Microsoft Word. Then uploaded that .html file which had 800 lines. HtmlWasher cleaned up all the file content, the endless meta tags, non sense IE style tags, etc.
Good launch and good start. All 3 stages complete. It's in space in a matter of seconds. Need another 45 mins to declare launch success and 10 months to reach mars!
