Add support for Metamask Mobile

[IgorShadurin]

Currently, our implementation only supports login with the Metamask Chrome extension. To broaden our user base and improve user experience, I propose implementing support for Metamask Mobile.

This will involve integrating the Metamask SDK into our app, which will provide additional authentication options such as using a mobile device or a PC without a Chrome extension but using a QR code, among other features.

This feature will need thorough testing across various scenarios and environments. Here are some test cases to consider:

• Login with wallets that are not connected to the site.
• Login with wallets that are already connected to the site.
• Login in incognito mode.
• Testing in mobile browsers with the same cases.
• Test login with QR code.
• Test across different browsers.

How much effort would this require ?

I'm trying to do this. At first glance, everything seems simple, but in fact, there are problems in some cases with the mobile version. I'm trying out different approaches.
