Use fake popups instead of system popups

[guyonvarch]

Using popups, it was hard to test the kiosk without setting up PlayOS VM.

Aditionally:

• use only one webview,
• decorate as dialog when necessary,

There should be no visual changes.

See https://trello.com/c/SJNLN2OJ/1550-playos-dialog-less-settings-and-captive-portal

Tests

• Using local captive portal on VM, I can click on the message when settings are open.
• With shed-key, use proxy of external server with basic auth.

networking.firewall.allowedTCPPorts = [ 1234 ];

services.tinyproxy = {
  enable = true;
  settings = {
    Port = 1234;
    Timeout = 600;
    Listen = "0.0.0.0";
    Allow = "12.13.87.my-ip";
    BasicAuth = "user password";
  };
};

Adapting the last commit message, wrongly saying it was not possible to open the captive portal when settings was open, as this OK on develop.

[guyonvarch]

• Think about scenario with captive portal + proxy.

[ ] Think about scenario with captive portal + proxy.

We should expect no difference, as the proxy is set application wide.

Checked

• proxy on shed stick,
• captive portal on shed stick,
• captive portal banner can be interacted with if config dialog is visible,
• key combos (Ctrl-Shift-F12, Esc) on shed stick work,
• kiosk running as one window on dev machine.

Nice 👍

@guyonvarch If I understand the question correctly, there should be no change and therefore no new issue in the interaction between proxy and captive portal checks. Feel free to merge if you agree, or let me know if there is another angle that I may be missing.

Exact.

One difference from before is that we take care of authentication for the captive portal as well:

https://github.com/guyonvarch/playos/blob/b59200ef4d608388937b2069e5b7bd20beb9990b/kiosk/kiosk_browser/browser_widget.py#L41-L44

I think it makes more sense now than before, as before we setup the proxy, but it would have failed if it required auth for the captive portal.
