Prepare frontend apps for React 19 and React Compiler

[ravicious]

Upgrading the codebase to React 19 should allow us to enable React Compiler, which not only should make the app faster, but also remove the need to remember about useCallback and useMemo where it counts.

Read through the upgrade guide, remember about codemods which should make some work much easier.

• Remove findDOMNode usage.
  • Remove findDOMNode usage from Modal and Popover #46123
  • Menu: Replace findDOMNode with a ref #46589
  • Add nodeRef to Transition to avoid use of findDOMNode #46590
  • Remove findDOMNode in Popover/Transition.jsx.
    • This should be taken care of by Bartosz's work on new popovers, but that's still in progress. WIP is on bl-nero/tooltips.
    • <Transition> is just one small component, so in theory we could extract a small PR from Bartosz's WIP that just removes findDOMNode from <Transition>.
  • Remove findDOMNode from ignored warnings.
• Remove defaultProps and propTypes from function components.
  • • Those are okay to have on class components. Affected components should print deprecation warnings in the console.
• Check if 3rd party deps, (e.g., React select) throw any errors.
  • So far I don't think they've been emitting any deprecation warnings, so they should be okay.
• Check if we have to worry about errors not being re-thrown.
  • boot.tsx in teleterm.
• Check if app is ready to be used with React Compiler.
