fix(ui): edge case resulting in no node templates when loading workflow, causing failure

Depending on the user behaviour and network conditions, it's possible that we could try to load a workflow before the invocation templates are available.

Fix is simple:
- Use the RTKQ query hook for openAPI schema in App.tsx
- Disable the load workflow buttons until w have templates parsed
