Add internal terminology defining and routines

[mrose17]

and some extra verbose output

Fixes #6531

Test Plan

1. run with LEDGER_VERBOSE=true
2. visit some sites, etc.
3. go to about:preferences#payments
4. some time later you'll see something that looks like the output below (sorry, it doesn't look "nice" in a variable-width font).
5. verify that things look "right" according to https://github.com/brave/browser-laptop/blob/issue-6531/app/ledger.js#L22 et. seq.

After removing synopsis list I've got the following error regarding this line:

TypeError: Cannot read property 'forEach' of undefined
    at run (/Users/cezaraugusto/dev/browser-laptop/app/ledger.js:1576:20)

@cezaraugusto - good catch, fixed, thanks!

Awesome job- this is nice 😄 Gave it a mild run and toggled sites and verified their status was updated correctly. Could definitely use some tests though...
