Add more wallets to login on the WeedWallet

[TJ-BitCanna]

Now we "only" have Keplr to log in.

Enable more major wallets from the ecosystem like CosmoStation & Leap.

(for future reference: we also need to keep an eye on how the integration of Cosmos-based chains in MetaMask is progressing, otherwise that would also be a nice move. But only for future reference.)
