minor fixes to react render

[dinmukhamedm]

1. Update route using useEffect because on some loads there was a warning about setting state while rendering
2. Force type cast instead of convert so that we don't use Mono like it is not intended. This is hacky, but better than silently stringifying internal react.

[!IMPORTANT] Fixes rendering warning in EvaluationsGroupsBar and enforces type casting in MonoWithCopy.

• Behavior:
  • Use useEffect in EvaluationsGroupsBar to update route after rendering, preventing state-setting warnings.
  • Force type cast children to string in MonoWithCopy to ensure correct usage, avoiding silent stringification.
• Files:
  • evaluations-groups-bar.tsx: Wraps router logic in useEffect.
  • mono-with-copy.tsx: Adds type casting for children prop.
