Correct custom hostname, port and ssl setting

[softsimon]

Make sure that mempool.js is configurable with custom hostname, port and HTTP/HTTPS and WS/WSS.

• mempool.js defaults to HTTPS, it only switches to HTTP if the hostname contains the word 'localhost'
• umbrel.local requires port 3006 to be specified (you can fake this by entering hostname 'umbrel@local:3006', but the umbrel example omits this
• once these two issue are overcome, mempool.js is hardcoded to WSS, so even if type hostname 'umbrel.local:3006' the connection is over WSS, and needs to be WS
