feat: add custom records to NWC connector

[rolznz]

Adds custom records (mainly used for podcasting payments but could be other things) to the NWC connector.

There is no standard on how these should be passed. In the NIP-47 spec metadata can be returned, so I think it makes sense to keep the custom_records (custom TLVs) in a separate object inside the metadata object.

(I will link the NWC PR when it's ready)

Great! Just one little thing I noticed in your screenshot?

Is the encoding somewhat wrong here? (see App metadata)

[rolznz]

@reneaaron it's the :zap: emoji. It seems to also be encoded wrongly using the LNDHub connector.

I also saw this check is wrong (it's checking the message but using the podcast) and I can't actually see where the message field is being used - edit: it looks like it's just a bad copy-paste (as per the screenshot the message was not shown)

{transaction.boostagram?.message && (
            <TransactionDetailRow
              title={t("boostagram.message")}
              content={transaction.boostagram?.podcast}
            />
          )}

@reneaaron I wonder if the emoji issue is some side effect of using base64 decoding, do you have any idea?

[reneaaron]

@rolznz I'll try to debug it :+1:
