Simplify UX and enable answer role

[lherman-cs]

Changes:

• Remove status page in favor of simplicity and productivity
• Add disconnect button
• Properly clean up peerconnection and rtmp server
• Accordion item will show properly depending on the role
• Enable answer role

This is yet another UI changes. I'm so into Fyne right now, sorry 😊

Damn, amazing! Thank you @lherman-cs

I did get OBS working, I just need to update the docs though. My goal is to have the 'publish to browser' docs done this weekend :)
