Upgrade website to WSS #49
Description
Context
Right now the website connection is ws and not wss, meaning that it is not compliant with the browser standard as it blocks non secured websockets automatically. It works locally because it makes an exception for locally websockets, but as we want the deployed https://www.trickfirerobotics.org/mission-control/ to be able to connect with the rover.
How to implement
Look at the conversation below but basically, in src/viator_launch/launch/robot.launch.py for rosbridge_server, update the launch arguments like this https://github.com/TrickfireRobotics/urc-2023/pull/74/files#diff-f2c5990233054c4089185587ffbfa56fa714640b2162fac78126d9b6e4a3a943R35 .

i think rosbridge has some way to do it relatively easily
id like to avoid setting up nginx for something so simple
unfortunately the ros forums seem to be acting up so i cant check rn
oh

the library theyre using says this
When using a secure websocket connection (wss://) with a self-signed certificate, the connection from a browser may fail because it wants to show the “accept this certificate” dialog but has nowhere to show it. You must first visit a regular HTML page using the same certificate to accept it before the websocket connection will succeed.
(https://www.tornadoweb.org/en/stable/websocket.html)
thats stupid
ok but we can specify the cert files without nginx: https://github.com/RobotWebTools/rosbridge_suite/blob/1de68964d2cb0687284760ba45979ec2f584a5b9/rosbridge_server/scripts/rosbridge_websocket.py#L102
these parameters can be set via the launch file: https://docs.ros.org/en/jazzy/Tutorials/Beginner-Client-Libraries/Using-Parameters-In-A-Class-Python.html#add-an-entry-point
wait no
also found this while looking: https://github.com/RobotWebTools/ros3djs

they appear to be defined here: https://github.com/RobotWebTools/rosbridge_suite/blob/1de68964d2cb0687284760ba45979ec2f584a5b9/rosbridge_server/launch/rosbridge_websocket_launch.xml
not sure how to change those vars, im sure someone does tho
oh just like this: https://docs.ros.org/en/jazzy/How-To-Guides/Launch-file-different-formats.html#setting-arguments
ok you guys shld be able to setup websockets tls pretty easily
They can also be set in the config like this: https://github.com/TrickfireRobotics/urc-2023/pull/74/files#diff-f2c5990233054c4089185587ffbfa56fa714640b2162fac78126d9b6e4a3a943R35
