Feature suggestions: substrate wallet integration

[Gintma]

I noticed that Snowbridge currently only supports some Polkadot wallets. I suggest taking a look at Lunokit (https://docs.lunolab.xyz/), which supports all Polkadot wallets, including hardware wallets. Its features and usage are very similar to Appkit, the EVM wallet integration library used by Snowbridge.

Below is a screenshot of the wallet connection modal.

LunoKit was implemented in PR: Snowfork/snowbridge-app#193

It can be tested on https://staging-app.snowbridge.network
