[ML] Add responsive layout to Index data visualizer, fix doc count ch…

…art margin (#147137)

## Summary

This PR addresses #137257 and
better handles the layout when the screen width decreases. Changes
include:
- The css is now updating based on the body content width (which
window's width - side bar navigation's width).
- The link cards are shown in the bottom instead of on the right side
when the content width is smaller
- Refresh button will only show the refresh icon when the size is small
- Fix the doc count chart margin too big causing the chart 
- Fix wide time range display with sparse data

For reviewers:
- **kibana-design**: 2 `.scss` files were deleted

### Risk Matrix

Delete this section if it is not applicable to this PR.

Before closing this PR, invite QA, stakeholders, and other developers to
identify risks that should be tested prior to the change/feature
release.

When forming the risk matrix, consider some of the following examples
and how they may potentially impact the change:

| Risk | Probability | Severity | Mitigation/Notes |

|---------------------------|-------------|----------|-------------------------|
| Multiple Spaces&mdash;unexpected behavior in non-default Kibana Space.
| Low | High | Integration tests will verify that all features are still
supported in non-default Kibana Space and when user switches between
spaces. |
| Multiple nodes&mdash;Elasticsearch polling might have race conditions
when multiple Kibana nodes are polling for the same tasks. | High | Low
| Tasks are idempotent, so executing them multiple times will not result
in logical error, but will degrade performance. To test for this case we
add plenty of unit tests around this logic and document manual testing
procedure. |
| Code should gracefully handle cases when feature X or plugin Y are
disabled. | Medium | High | Unit tests will verify that any feature flag
or plugin combination still results in our service operational. |
| [See more potential risk
examples](https://github.com/elastic/kibana/blob/main/RISK_MATRIX.mdx) |
