Persist wallet connection

[jeremy-babylonlabs]

We could store wallet connection status in localStorage / sessionStorage as a map

could be something like this (rough idea)

interface WalletConnectionMap {
    [key: string]: WalletConnectionDetails;
}

interface WalletConnectionDetails {
    accounts: string[];
    connector: WalletConnector;
    current: string;
    ttl: Date;
}

interface WalletConnector {
    id: string;
    name: string;
    type: string;
    uid: string;
}
