update frontend to support module federation

[christianvogt]

Description

Builds on top of #793

• Updates the frontend to always call the api with a prefix: /model-registry/api/vi. Required a change to BFF to support this.
• Added a stub module federation configuration but do not yet expose any APIs.
• Updated the webpack configs to support module federation with publicPath: 'auto' then other path updates to ensure standalone and integrated use cases continue to work.
• The change to index.tsx and bootstrap.tsx were necessary for module federation

How Has This Been Tested?

Follow the instructions under clients/ui/docs/kubeflow-development-guide.md
Tested frontend dev and build modes.

While module federation has been included and tested in a dev environment, exposing APIs has been omitted from this PR. There is currently no test or use case implemented yet for module federation support.
