fix(docs): mastering-accounts

[danforbes]

Streamline Mastering Wallets & Accounts (and rename it to Introduction to Accounts & Wallets). Try to make this page more focused and easier to understand. Remove a lot of the material that is present on other pages and replace it with a "Next Steps" section.
