Add LNbits payment processor

[Semisol]

Description

Adds the LNbits payment processor. Also includes:

• small refactoring changes
  • BigInt -> bigint on files that I have touched
  • use utility functions to create PaymentsServices instead of manually doing it
• migration to switch invoice IDs to TEXT
• callback refactoring

Related Issue

Closes #163

Motivation and Context

Allowing users to receive pay to relay payments via alternative methods/to their own node.

Tested on production with atlas.nostr.land. Would prefer someone else tests this too.
