feat(server): add support for loading configuration from a remote home control plane

- Introduced `-home` and `-home-password` flags for specifying home control plane address and authentication.
- Implemented fetching and parsing configuration from the home control plane when `-home` is used.
- Adjusted server configuration handling to bypass local config files when loading from home.
- Ensured compatibility with cloud deploy mode and validation of home configurations.
