Migrate to react-redux v8 with a typed AppDispatch / useAppDispatch #39927

Sub-issue of #39890.

The react-redux v7 → v8+ bump turned out to be larger than the parent issue anticipated. Tracking it separately so it doesn't block the rest of the React 18 concurrent-feature adoption work.

Why it's not a one-line bump

v8 tightened useDispatch() and connect's Dispatch typing so it no longer auto-accepts thunks. A representative sample (just SqlLab/components/EditorAutoSync/index.tsx, PopEditorTab/index.tsx, QueryTable/index.tsx) surfaced ~50 new errors of these shapes:

error TS2345: Argument of type 'SqlLabThunkAction<X>' is not assignable to parameter of type 'AnyAction'
error TS2344: Type '(dispatch: any) => Promise<…>' does not satisfy the constraint 'Dispatch<AnyAction>'

Across the full codebase the affected call sites likely number in the hundreds. The proper fix is the redux-toolkit-recommended pattern:

// in src/views/store/index.ts (or wherever the store is exported)
import { useDispatch, useSelector, type TypedUseSelectorHook } from 'react-redux';
import type { ThunkDispatch } from 'redux-thunk';
import type { AnyAction } from 'redux';

export type AppDispatch = ThunkDispatch<RootState, unknown, AnyAction>;
export const useAppDispatch: () => AppDispatch = useDispatch;
export const useAppSelector: TypedUseSelectorHook<RootState> = useSelector;

…then migrate useDispatch() → useAppDispatch() and useSelector(...) → useAppSelector(...) across all consumers.

Suggested approach

1. PR 1: Define the typed hooks alongside the existing store, don't migrate any call sites. Verify it compiles and exports cleanly.
2. PR 2…N: Migrate one feature area per PR (SqlLab, dashboard, explore, components, …). Each PR gets the typed-dispatch swap and the v8 bump applied to that slice's typecheck closure.
3. Final PR: Bump react-redux in package.json, remove @types/react-redux from the three places it's declared (it's bundled with v8), drop any leftover Dispatch<AnyAction> assertions, verify full project typechecks.

Alternative: a single mega-PR that does all of it at once. Higher review burden, harder to revert, blocks other work — generally not recommended unless someone wants to drive it as a focused effort.

Why this isn't blocking #39890

useDeferredValue works fine under react-redux v7. The "tearing risk" mitigated by v8's useSyncExternalStore only manifests with useTransition, so useTransition adoption (parent issue's tier-2 item) is what actually depends on this. We can ship useDeferredValue migrations against v7 in the meantime.
