QOL Improvement: Improve SKALE Bridging Token Selection UI

[TheGreatAxios]

Background

When going to bridge you will notice that you have many tokens cut-off.
I think it would make sense to have the tokens wrap horizontally so that you can have multiple on a single line

Updates

1. Add a Search Bar
2. Add "Your Tokens" or similar at the top which checks for balances

I actually prefer Sushi Swap format here. I like the "Search" as the first piece, popular tokens right under, and then my tokens next.
