[Tech Debt] Reorder Rule Details page

[CoenWarmer]

Resolves #152791

Summary

This PR updates the Rule Detail Page to follow the newly agreed upon structure for the Observability app.

This PR is part of a larger effort to have all pages in the Observability app follow the same structure so they are more consistent with each other. More details in the epic: #152783

It also cleans up dead and unused components where found.

All design and functionality should be exactly the same as before.

Investigating why the bundle increased so much with this PR.
