Redirect to webpage when querying payment pointer in browser

[golobitch]

When querying payment pointer, we are always returning JSON data about that payment pointer.

For example, when entering ilp.dev/007 in URL we get following response:

{
    "id":"https://ilp.interledger.cards/007",
    "publicName":"Tadej Golobic",
    "assetCode":"EUR",
    "assetScale":2,
    "authServer":"https://auth.interledger.cards",
    "resourceServer":"https://ilp.interledger.cards"
}

Idea is, when querying payment pointer through browser (meaning when Accept header is text/html), we should redirect user to a webpage with a 301 status code. This redirect URL should be defined in the environment variables (exactly like it is for idp).

Example wallet address: https://fynbos.me/radu
Example of the page after navigating to wallet address in browser: https://interledger.app/me/fynbos.me/radu

It should be implemented here:

rafiki/packages/backend/src/open_payments/wallet_address/routes.ts

Line 32 in a501fce

export async function getWalletAddress(

in getWalletAddress we need to check if Content-Type is text/html. If it is, then we need to do redirect to the webpage defined in env.

This needs interledger/open-payments#550 to be merged, then updated here on the todo comment to use the newest openapi spec for response validation middleware
