Update React to v18

[kmcginnes]

Description

• Updates React to v18
  • Changed root render calls to the new style
  • Fixed stricter type requirements
  • Moved off deprecated types
  • Fixed key prop being set by object spreading
• Updates all React components to latest
  • Mantine jumped two versions and needed adjustments
  • The drag and drop lib react-dnd needed some slight adjustments
• Fixed existing issue exposed by the React v18 upgrade of a runaway useEffect that fires way too often
  • Moved the logic in to a component that is conditionally shown so that the useEffect is no longer necessary. The state that was updated is set when the component is shown, which is all that is needed.

Validation

Essentially, nothing should change from a user's perspective. This is purely a regression test.

Focus On

• Modals
• File inputs
• Export from table (nodes and edges)
• Drag and drop (search results to graph, connection file to connections)

Review Suggestions

Given the size of this change set, I would recommend reviewing the code changes commit by commit. It may also be useful to enable the "hide whitespace" in GitHub.
