Configuration module for MagicAuth.

This module provides functions to access configuration values for the MagicAuth library. It handles default values and required configurations.

Configuration Options

• :repo - (required) The Ecto repository module used by your application.
• :router - (required) Your application's router module.
• :callbacks - (required) Module implementing MagicAuth callback functions.
• :endpoint - (required) Your Phoenix application's endpoint module.
• :remember_me_cookie - (required) Name of the cookie used for "remember me" functionality.
• :get_user - required only if you want to use the current_user assign in your LiveView / Controllers. If you are returning {:allow, user_id} from the log_in_requested/1 callback, you need to configure the get_user function to retrieve the user.
• :repo_opts - (optional, default: [magic_auth: true]) Options passed to repository calls. Can be a keyword list or a function that returns options. Passing a function is useful to pass options that are dependent on the current environment. For example, you can pass a function that returns the current tenant prefix: fn -> [prefix: MyApp.Repo.get_org_id()] end.
• :one_time_password_length - (optional, default: 6) Length of generated one-time passwords.
• :one_time_password_expiration - (optional, default: 10) Expiration time in minutes for one-time passwords.
• :remember_me - (optional, default: true) Whether to enable "remember me" functionality.
• :session_validity_in_days - (optional, default: 60) How long sessions remain valid.
• :enable_rate_limit - (optional, default: true) Whether to enable rate limiting for authentication attempts.
