feat: add password field to RealityObject interface and update publicKey retrieval logic

- Introduced a new optional 'password' field in the RealityObject interface to enhance configuration options.
- Updated the logic in FormatHostsService to retrieve the publicKey from realitySettings, falling back to the new password field if publicKey is not available.
