After marking a task instance as success/failed/skipped, the state badge
on the task instance detail page does not update until a manual page reload.
The root cause is in `usePatchTaskInstance`: the `GetMappedTaskInstance`
query was invalidated using the full 4-field key
`UseTaskInstanceServiceGetMappedTaskInstanceKeyFn({ dagId, dagRunId,
mapIndex, taskId })`.
While this exact key should theoretically match, TanStack Query's
`partialDeepEqual` matching is more reliable when the search key is a
**subset** of the cached key rather than an exact match.
`usePatchDagRun` already uses the partial-key pattern for the same query:
```ts
[useTaskInstanceServiceGetMappedTaskInstanceKey, { dagId, dagRunId }]
```
This PR aligns `usePatchTaskInstance` to the same approach, using
`[useTaskInstanceServiceGetMappedTaskInstanceKey, { dagId, dagRunId, taskId
}]`
as a partial key that matches any `mapIndex` for the given task. This also
eliminates the separate predicate-based invalidation that was needed for the
"patch all mapped TIs" case (`mapIndex === undefined`), simplifying the code.
closes: #67883
