Library does not run on React V19

Finch is built on React V18, it doesn't work on React V19 after doing an npm install and trying to call a component.

-For now, add dependency requirement where version must be <19 so we don't install if it won't run
-Long term, support both V18 and V19 by either:
  -A) Switch to developing in V19 and test builds in V18
  -B) Add some configuration to allow building in V18 while supporting V19
