Merge remote-tracking branch 'origin/main' into remove-n8n-network-dependency

- Remove complex file-based secrets system and secureCredentials.ts
- Switch to standard .env file approach for all credentials
- Update all code to use process.env directly instead of secureCredentials
- Remove docker-compose.secrets.yml and setup-secure-credentials.sh
- Update tests to use environment variables directly
- Simplify Docker Compose configuration to use env vars

This change reduces complexity while maintaining the same security level,
as both approaches store plaintext credentials on the host. The .env
approach is simpler, more standard, and easier to manage.
