Wallet connect button - Githubissues

Implementation details

add styling according to figma (it's called "Switch account" but it should be "Connect Wallet" until wallet is connected)
make sure to display connected address (design pending)
component should be hidden until source network is selected
if evm network is selected, display webonboard (at least Metamask and WalletConnect should be supported)
if substrate network is selected you need to create own popup (to choose between different wallet extensions and WalletConnect). Maybe we can reuse https://polkadot.cloud/overview
