feat: Add password generation and testing scripts

- Add generate-password.js for Node.js password hash generation
- Add generate-password-docker.sh for Docker-based generation
- Add test-password.sh to verify password against current hash

These scripts help users generate correct bcrypt hashes for the
ADMIN_PASSWORD_HASH environment variable.

Usage:
- Generate new hash: ./scripts/generate-password-docker.sh
- Test current password: ./scripts/test-password.sh
