Credit card blacklist

Any card on the list is just treated as though it is not present, preventing it

Customer Financials

I've pulled out information about payment methods and bitcoin into its
own thing. It's kind of a repository, except that it only exposes
fetchers and doesn't load anything generally.

There's also a few new methods here that aren't used yet, but will be
shortly.

Remove BigDecimal.new

It turns out in newer versions of Ruby this isn't cool anymore.
The new way is BigDecimal(value), which is dumb, but whatever...

Customer always has a JID

Validate that amount of credit to buy is in valid range

Fix sentry issue SGX-JMP-4

Typo not caught by tests because this method had none.  Add a test, fix the typo.

Refactor BuyAccountCreditForm

add_to_form no longer needs a promise or a network call, instead we use
a factory to get that data up front and inject the dependency.

New BuyAccountCreditForm#parse to get the relevant data back out of an
XMPP form.

Some changes to Transaction and sgx_jmp.rb to use the new method
semantics.

fix ci

New signup: go to web to choose credit card

This step, if chosen, directs the user to the jmp-pay webapp to add a credit
card.  It includes an OOB element for use by user agents that can handle
that (possibly for webview embed, etc) with a note-based fallback as per XEP.
Once the user chooses "next" the code checks if they have actually added a card,
and if so continues to a yet-unimplemented step and if not repeats the
instruction to go to the web app.

Split logic out into testable objects

Rubocop clean. Good test coverage of helper objects.
