Add externally connected wallets into Paima

[SebastienGllmt]

This PR reworks the wallet connection mechanism to allow including wallets that were initialized externally to be use by Paima. You can find the docs on this here

Bug fixes

• Fix start.sh docker script being broken
• Fix message signing for Nami wallet
• Fix wait for emulated blocks throwing instead of waiting
• Fix named connection type for Etheruem potentially missing a wallet if that wallet implements multiple injection standards
• Fix some wallets aggressively adding themselves as the default even if a user has never installed it (ex: Brave's built-in crypto wallet)

Features

• Allow multiple providers to be connected at once. Useful if you want a browser wallet connected to Paima at the same time as a session key
• Add a way to specify "default" connector to be used unless explicitly told not to (useful to make the session key the default)
• Add support for any Ethers Signer (@ethersproject/abstract-signer) based wallets
• Add allInjectedWallets to get all the injected wallets of every cryptocurrency Paima supports at once

Breaking changes

• getAddress on connectors now returns a struct to specify the address type (instead of just the address string)
• userWalletLogin parameters changed
