drying machines

[mango-habanero]

0.1.0-alpha is a POC largely geared toward getting the machines more maintainable and keeping them separated, hence a bunch of the code is repeated, this issue will address making these components more generic across all machines.

• [x] move all pin validation into the auth machine.
• [x] standardize machine errors.
• [x] move all inter-account interactions to a generic validation function.
• [x] add better state descriptions.
• [x] put all generic terminal states in base translation files i.e
  • account blocked
  • exit
  • main menu
