[Mgmt] Remove usage of deprecated modules for mounting React, Part II (#182043)

## Summary

Partially addresses https://github.com/elastic/kibana-team/issues/805

These changes come up from searching in the code and finding where
certain kinds of deprecated AppEx-SharedUX modules are imported.
**Reviewers: Please interact with critical paths through the UI
components touched in this PR, ESPECIALLY in terms of testing dark mode
and i18n.**

This is the **2nd** PR to focus on code within **Kibana Management**,
following https://github.com/elastic/kibana/pull/180331.

Note: this also makes inclusion of `i18n` and `analytics` dependencies
consistent. Analytics is an optional dependency for the SharedUX
modules, which wrap `KibanaErrorBoundaryProvider` and is designed to
capture telemetry about errors that are caught in the error boundary.
