[Console Monaco migration] Fixes (#186479)

## Summary

Fixes https://github.com/elastic/kibana/issues/184927
Fixes https://github.com/elastic/kibana/issues/184584
Fixes https://github.com/elastic/kibana/issues/184447


This PR fixes various issues in the migrated Console: 
- The url params with whitespaces are now parsed correctly and the whole
values is sent in the request
(https://github.com/elastic/kibana/issues/184927)
- The autocomplete for fields only shows the fields of the current index
(https://github.com/elastic/kibana/issues/184584)
- The popup with autocomplete suggestion is not covered by the resizer
bar (https://github.com/elastic/kibana/issues/184447)

#### How to test
1. Send a request with a url param that contains a whitespace, for
example `GET _search?q="test test"`. The request should be executed
correctly.
2. Create an index with only 1 field 
```
PUT field_test/_doc/1
{
  "test": 1
}
```
Try a search query with the fields autocomplete and check that only 1
field is suggested
```
GET field_test/_search
{
  "query": {
    "match": {
      "
```
3. Check that the popup with autocomplete suggestions is not covered by
the resizer bar

### 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—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—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. |

examples](https://github.com/elastic/kibana/blob/main/RISK_MATRIX.mdx) |
