Force native EventTarget event dispatching on for the React renderer - #59911

## Summary: react#59896 removed `enableNativeEventTargetEventDispatching` from `ReactNativeFeatureFlags`, but the vendored Fabric renderer still reads it through `react-native/react-private-interface` to choose between `dispatchNativeEvent` and the legacy plugin-based dispatch. With the getter gone, the renderer saw `undefined`, treated the flag as off, and fell back to the legacy path, so listeners registered with `addEventListener` were never called. The `ReactNativeFeatureFlags` getter in the private interface now returns the real flags plus `enableNativeEventTargetEventDispatching: () => true`, so only the renderer sees it. This can be removed once the renderer is synced from a React build that no longer reads the flag. ## Changelog: [Internal] ## Test Plan: - `yarn fantom packages/react-native/src/private/renderer/core/__tests__/EventTargetDispatching-itest.js`: 16 failures before, 78 passed / 20 skipped after. - `yarn fantom packages/react-native/src/private/webapis/dom packages/react-native/src/private/renderer`: 513 passed, 26 skipped. - `yarn eslint --max-warnings 0` and `yarn prettier --check` on both changed files pass. - `yarn flow-check` reports only 2 unrelated parse errors from local git ref logs under `.git/logs/refs/remotes/` whose names end in `.json`. 🤖 Generated with [Claude Code](https://claude.com/claude-code)

Wouldn't this force all the properties to materialize? Why not add it back to the react feature flags config with default true? |

They'd be materialized anyway, but it's only the accessor functions, not the underlying flag read. |
Summary: react#59896 made `ReactNativeElement` unconditionally extend `EventTarget`, which imports the `AbortSignal` type, pulling `AbortSignal.d.ts` into the generated types checked by `yarn test-generated-typescript`. The internal `abortSignal(reason = ..., signal)` helper declares a defaulted parameter before a required one, which flow-api-translator emits as `abortSignal(reason?: unknown | void, signal: AbortSignal)` and tsc rejects with TS1016. Reorder the parameters to `abortSignal(signal, reason = ...)` and update both internal callers. The public API snapshot is unchanged. Changelog: [Internal] Test Plan: - `yarn build-types --skip-snapshot && yarn test-generated-typescript`: fails with TS1016 before, passes after - `yarn build-types --validate`: API snapshot is up to date - `yarn eslint --max-warnings 0 packages/react-native/src/private/webapis/dom/abort-api/`

## Summary: react#59797 added `experimental_onSafeAreaInsetsChange` to the root `logbox_inspector` view, and react#59893 refreshed the LogBox snapshots without that change, so both landed but the committed `LogBoxInspector` baseline is missing the prop. The two inspector snapshot tests fail in Fantom CI mode, which no longer rewrites mismatched baselines (react#59895). Regenerate the two affected snapshots; the only change is the added prop on the root view. ## Changelog: [Internal] ## Test Plan: - `CI=true yarn fantom packages/react-native/Libraries/LogBox`: 2 snapshot failures before; 90/90 tests and 54/54 snapshots pass after, on two consecutive runs. 🤖 Generated with [Claude Code](https://claude.com/claude-code)
