🚨 Severity: CRITICAL
πŸ’‘ Vulnerability: Hardcoded default secrets (database password and encryption key) in Docker configuration files (Dockerfile, docker-compose.yml).
🎯 Impact: If the application were deployed using the default configuration, it would use known, weak credentials, making it highly vulnerable to unauthorized access and compromise.
πŸ”§ Fix: Removed all hardcoded default values and fallbacks for secrets from the Dockerfile and docker-compose.yml. The application will now fail to start unless these secrets are provided via environment variables (e.g., a local .env file), enforcing a secure configuration.
βœ… Verification:

  1. Inspect Dockerfile: Confirm that ENV definitions for DB_PASSWORD and ENCRYPTION_KEY have no default values.
  2. Inspect docker-compose.yml: Confirm that DB_PASSWORD, POSTGRES_PASSWORD, and ENCRYPTION_KEY are read from variables (e.g., ${DB_PASSWORD}) and have no :-changeme fallbacks.
  3. Attempt to run docker-compose up without a .env file. The server container should fail to start due to missing environment variables.

PR created automatically by Jules for task 11611073938290474266 started by @richkmeli

Removes default credentials and secrets from the Dockerfile and docker-compose.yml to prevent insecure deployments.

- Removes default 'changeme' values for DB_PASSWORD and ENCRYPTION_KEY from the Dockerfile.
- Removes fallback values for DB_PASSWORD and POSTGRES_PASSWORD in docker-compose.yml.
- Adds ENCRYPTION_KEY to the server service environment in docker-compose.yml to ensure it is passed to the application.
- Updates .env.example to guide users to set their own secure passwords.

This change enforces a secure-by-default configuration.
