When LOCALAI_PREFER_DEV_BACKENDS is set, install the -development image as the
primary backend URI (keeping the released image reachable as the first
fallback), instead of only reaching development as a download fallback when the
released image is missing. This lets an operator force backends built from the
development branch — e.g. to pick up a fix already on master before a release.
Threads PreferDevelopmentBackends through SystemState so InstallBackend can see
it, and reuses the same development-URI convention as the existing failure-path
fallback (released tag -> branch tag + dev suffix). The unexported developmentURI
helper is covered by a Ginkgo spec.

- Add a system backend path
- Refactor and consolidate system information in system state
- Use system state in all the components to figure out the system paths
to used whenever needed
- Refactor BackendConfig -> ModelConfig. This was otherway misleading as
now we do have a backend configuration which is not the model config.
