Fix react-query mutation typing for v5.90

Summary

• Update the React Query generator to support the current UseMutationOptions signature from @tanstack/react-query (the fourth generic now represents onMutate results; mutation callbacks receive an extra context argument).
• Simplify the generated useRapiniMutation helper so it forwards callback arguments transparently, removing hard-coded parameter lists and keeping future TanStack changes from breaking the wrapper.
• Adjust the mutation generator and specs to emit the new helper call-site signature and assert the expected TypeScript output.

These changes are necessary for react-query versions v5.89.0 and newer, as mentioned in TanStack/query/ issue 9660:
v5.89.0: onError, onSuccess and onSettled signature change breaks existing code and were created with the help of an AI agent.
