Make the verifier work as web application

[andrea-dintino]

[EDIT 16.10.24] probably this requires websocket @puria

The verifier app, when running on mobile, needs Firebase to receive communications.

In order to run it as a web app, we need basically to:

1. In the Verifier:

• expose a route like /verification and map it on the Slangroom script that currently executes what is returned from Firebase
• maybe (maybe not) some work needs to be done pass the output into the notification/history array
• the QR code must be generated differently, specifically:

{
  "relying_party": "https://relying-party1.zenswarm.forkbomb.eu/relying_party/",
  "t": "https://verifier.myserver.com/verification",   <-- here goes the endpoint created above, with the URL that can be read from .env
  "exp": 1570000000,
  "m": "w",   <-- the "w" stands for "web" and this will help the Relying party understand how to communicate with the Verifier-web
  "request_uri": "https://admin.signroom.io/api/collections/templates/records?filter=%28id%3D%222rn9c5rfu54bwjw%22%29&fields=schema"
  "sid": "abcde",
  "id": "k86672rkeyfe9h7"  
}

Some minor facelift must be done in the GUI to make it look ok on a 16:9 screen - but no sweat here :-)

2. In the Relying Party:

• There should be an IF ("m" == "w") then {pass the response via REST to "t"}

And I guess that we're good to go
