WatchedQuery Bug Fixes

[stevensJourney]

Overview

This PR fixes several bugs and regressions introduced with Incrementally Watched Queries.

For background, see this Discord thread.

Updating Watched Query Settings

This addresses a race condition that could occur when updateSettings was called multiple times on the same WatchedQuery instance.
The changes improve how AbortController lifecycles are managed, ensuring that updates from linked queries do not execute simultaneously.

Previously, this could cause isFetching to briefly report false before toggling back to true when query parameters changed.

React Hooks

In some cases, isFetching was reported as false immediately after changing query parameters: before the query had actually executed. This made handling state in useQuery unreliable.

This PR fixes the issue by applying the same approach that was previously implemented here.
