Add Health command for security assessment and vault hygiene checks

[mikeleppane]

• Introduced the Health command to analyze vault security, detecting weak, reused, short, common, and old passwords.
• Implemented handle_health_command to evaluate vaults and calculate a security score with detailed issue breakdowns and recommendations.
• Replaced anyhow with color-eyre for enhanced error handling across the workspace.
• Updated imports and error messages to use eyre for consistency.
