Update dependencies + clean up

[benface]

This PR:

• Updates dependencies, including @edgeandnode/go to have the latest NetworkIcon component.
• Temporarily hides Ultra from the supported networks grid on the home page since web3icons doesn't support it yet.
• Makes supported networks clickable on the home page.
• Slightly improves the performance of searching for a network on the Supported Networks page, by debouncing the value.
• Attempts to remove complexity in the code by removing unused code (e.g. SkeletonRow) and merging files together, increasing colocation and removing the need to name things in a similar and potentially confusing manner (e.g. NetworkPage and NetworkDetailsPage, or NetworksTable and SupportedNetworksTable).
• Groups the scripts that should be run together in CI into a single prebuild:ci script. This can also be run locally, but the resulting changes (if any) should not be committed.

I just added ultra to web3icons, and opened a pr to networks-registry (turns out ronin was also missing an icon)

this cannot be "fixed" unless zora decides to gives us a mono logo, we should just delete this todo imo
