Return type of useSendUserOperation is inconsistent with useMutation return type

[freeatnet]

Steps to reproduce:

1. Use useSendUserOperation hook.
2. Inspect result.data in a branch where result.isSuccess is true.

Expected: based on original react-query types, when isSuccess is true, data should have TData type.
Observed: data is TData | undefined.

Same issue applies to isError and error.

Quick triage suggests original types get mangled by Omit<UseMutationResult<…>, 'mutate'>. Wagmi seems to use a custom UnionOmit utility type to deal with the same problem.
