feat: add rate limiter

[vn7n24fzkq]

• Add rack_attack as a rate limiter.

• Add config/initializers/rack_attack.rb for rack_attack.

  • Allow2Ban: Ban a user if they attempt to log in 10 times within 1 minute, for 5 minutes.
  • Throttle: Limit requests to 100 requests per 5 minutes, exclude assets requests.

• Add a docker-compose file including a PostgreSQL service to simplify building a local development environment.

• Host the web server on 0.0.0.0 in the Docker container, allowing access via localhost.

• Change the RubyCache control condition. Now, you can enable the cache in development by setting the environment variable RAILS_DEV_CACHE to true.

Please note that the Dockerfile hosts the server on 0.0.0.0. I am not sure how this will affect the deployment on Zeabur.

Zeabur used 0.0.0.0 as well.
