new high availability lightning node setup:

- core-lightning node on a VPS

- swapped the bitcoind blocksource with sauron (esplora plugin)

- created a load-balanced nginx config that has 3 upstream esplora nodes: my node at home over wireguard, blockstream.info, mempool.space

this is slick because it makes running lightning nodes a breeze, no crazy storage requirements needed on your server.
