Wallet definitions with uniform interface

[ekzyis]

Description

This replaces all attached wallets with definitions that use a uniform interface.

The wallet definitions export following properties:

• name: the wallet name. will be used as a wallet identifier across the code (used with useWallet etc.)
• fields: this defines which fields are required to configure this wallet
• card: properties for use with WalletCard
• validate: will be called to validate configuration before saving it
• schema: schema for formik validation
• sendPayment: for wallets that support sending
• createInvoice: for wallets that support receiving
• ... tbd

Other changes

• replaced occurrences of WebLN with Wallet: useWebLN -> useWallet

For this:

[ ] receiving wallets (server)

I began doing this in #1178 in api/createInvoice

edit: there's no regard for the frontend code though ... purely a backend thing, so maybe not super relevant
