VYZN: As a user I can launch the vyzn app from Bldrs

As a user I can launch the vyzn app from Bldrs

Workflow

1. Open Bldrs
2. Start vyzn app
3. Vyzn app loads

SSO or loading the proper ifc model is not in the scope here.

UI

When the URL &appstore=true is supplied to Bldrs perform the following changes in the UI:

1. Add an app-store icon here in the right panel
2. When clicking the icon the right panel toggles on/off

The panel should contain the following content:

Scope:

• Initially use a custom HTML page inside the iframe instead of prod.vyzn.tech
• In Bldrs store the current uploaded file in Local Storage of the browser so that the raw file remains available for vyzn later on. Currently the file is discarded by Bldrs.
• When launching the vyzn applet, transmit the raw file through the iframe boundary to the vyzn applet
  • This should be triggered by a Matrix Widget API message
  • If there is a github URL available then transmit the URL as well (the data is discarded at the moment)
• The applet show allow the user to
  • chose a project from a dropdown ("Projekt")
  • chose a building from a dropdown ("Gebäude")
  • hit the button "import"
    • this should close the applet and open vyzn in fullscreen (navigated to project > building)

The iframe concept has already been explored in a prototype:

• VYZN in BLDRS: App Container for testing #379
• https://deploy-preview-379--bldrs-share.netlify.app/share/v/p/index.ifc#c:-111.37,14.94,90.63,-43.48,15.73,-4.34

This issue should be split later on.
