Walnut Lite: Visualisation of supported chains

[mazurroman]

This issue is about this section:

The visual is looking great already! I really like how the cards "float" making a "live" appeal. But we would like to introduce a notion of support for "maaaaaany" chains, not just four.

Some of the cards are currently less visible than others. That creates an idea: can we have cards "appear" and "disappear", in time? To create a visual impression that the user is debugging many transactions across many different chains?

Displaying 20 cards at the same time would be too much. So what about we keep showing four (two full visibility, two less visibility) and then, over few seconds, some of the cards become more visible, while others fade away and get replaced by new cards.

We can have a loop of 20 cards or so that keep appearing and disappearing. At any given time, the page would show 3-4 cards.

Regarding the cards design:

• The "circle" will actually be a logo of each chain. I.e. Optimism Mainnet, Base, Zora, ...
• It would be good to have the "circle" a bit larger
• The tx hash: it's unclear this is a tx hash. We should probably make it a bit longer. @barabanovro would love to hear your thoughts
• The chain name is OK with the exception of "Custom RPC: https". @barabanovro any suggestion what to use in this case?

@melnikga please wait with implementation until we flash out the specs

• I would suggest adding more symbols to the transaction hashes and placing the ellipsis at the end (similar to how it's done on Etherscan). Additionally, use different hashes for each transaction. For example: 0x24d525cba511fr7...
• Use http://localhost:3000 instead of Custom RPC: https
