[kdelemme]

resolves #192176
resolves #192105

Summary

This PR introduces a form used for editing and creating an investigation. Currently, the only available fields are the title and the status.

I've also removed the ESQL datatable in this PR.

Testing

Go to the investigation page, use the Create button to create a new investigation, then edit it. Add some esql items and notes.
