dev: skip Slack verification in development mode

[joan-code6]

This pull request introduces a Docker Compose setup for local development and adds a development-only shortcut for authentication that creates a test user and session when running in a development environment. These changes streamline the development workflow by simplifying database setup and enabling quick login for developers.

Development environment improvements:

• Added a docker-compose.yml file to set up a local PostgreSQL instance with persistent storage and health checks, making it easier to run the app locally without manual database setup.

Authentication enhancements for development:

• Updated the /login route in src/routes/auth.ts to automatically create and log in a test user with a session when NODE_ENV is set to development, bypassing the normal authentication flow for faster local testing.

Sry for AI slop I just don't know how to formulate it goodly...

It just bypasses the slack login when running through npm run dev and logs you instead in as a test user

I did this bc when testing my moderation system I would have had to configure slack and it's just annoying
