Create UI for managing AbandonAuth accounts

[fisher60]

Summary

Due to expanding functionality within the app, we are now in need of a simple UI to login to and manage abandon auth accounts.

We need a way to login directly to abandon auth accounts using the various OAuth methods. This UI should allow a persistent login session using a long-lived user JWT. When logged in, users should be able to create, read, update, and delete developer applications owned by the user (using existing API functionality).

Currently the plan is to use Jinja templates with tailwind for a very simple, SSR app.

Acceptance Criteria

• A UI exists that allows users to login to an AbandonAuth user account and store their login session as a cookie.
• Users can manage their developer applications from the UI (existing CRUD operations)

Login and logout UI complete, just need to add account management and (more importantly) developer application management, developer app endpoints already exist.

Reduced scope to only include basic account info and developer app CRUD
