Modernize PhortuneAccount with EditEngine/Modular Transactions

Summary: This updates the backend of PhortuneAccount to use EditEngine and Modular Transactions and updates language to "account manager" for clarity of role.

Test Plan:
- Wiped `phortune_account` table
- Visit Phortune, see new account automatically created.
- Edit name and managers
- Try to set no name or remove myself as a manager, get error messages
- Visit `/phortune/` and create another new account
