[Discover] Support overriding solutionNavId used for root profile r…

…esolution in embeddable (elastic#205986)

## Summary

This PR adds support for overriding the `solutionNavId` used for root
profile resolution within the Discover embeddable, allowing consumers to
force specific root profiles. Additionally the current usages of
`LazySavedSearchComponent` within Observability apps have been updated
to pass `solutionNavIdOverride: 'oblt'` to ensure their embedded logs
components render in logs mode as expected.

Resolves elastic#203121.
