Migration/fix Query Editor line jumping

[danburonline]

When trying to edit a query or create a new one, the active line jumps to the last line if you type. This PR fixes this issue.

Additionally:

• Cleaned and refactored touched components.
• Adjusted styles a bit.
• Moved the "Execute Elasticsearch query" button to the top right, as is the case with other code editor buttons in the Fusion app.

How has this been tested?

• Tested locally with dev server and prod build on my MacBook.

Types of changes

• Bug fix (non-breaking change which fixes an issue)

Checklist:

• I have added screenshots (if applicable), in the comment section.
