dropthejase rips out the login system and rebuilds it on AWS Cognito

This is the single biggest piece of work in the fork: dropthejase has replaced Supabase (a hosted authentication and database service) with Amazon Cognito, AWS's own user-management system, across the infrastructure, the back end, and the front end. The new setup ships with a stronger password policy and optional time-based two-factor authentication - the six-digit codes from an app like Google Authenticator - so accounts can be locked down harder than before.

The login, signup, and account-deletion flows were all rewritten to match, and deleting an account now cleanly cascades through the user's data. dropthejase is candid that the switch is expensive: anyone adopting it would have to migrate existing users, rewire every place the app checks who you are, and redeploy. If you're happy on Supabase, skip it.
