Show on-chain confirmation counter for channel-opening-TX

[myxmaster]

Describe the feature

When clicking on a pending channel, it would be cool to see the amount of on-chain confirmations for the channel-opening-TX.

Could use funding_expiry_blocks here

I wanted to get the number of confirmations first using this method: https://lightning.engineering/api-docs/api/lnd/wallet-kit/get-transaction

But when testing this with a local Polar LND node (0.17.5) I only get a 501 Not Implemented error. Any ideas?

@myxmaster this is a v0.18 endpoint https://github.com/lightningnetwork/lnd/blob/master/docs/release-notes/release-notes-0.18.0.md#rpc-additions

Ohh I see, thanks...
