Summary:

Remove enableNativeEventTargetEventDispatching and retain its enabled paths unconditionally. Preserve the separate enableImperativeEvents gate and existing test behavior. Test edits remove retired flag configuration and correct the typing required by the ungated EventTarget inheritance; no assertions or helper functions were added. Regenerate the public API snapshot for the permanent EventTarget inheritance.

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/`

* Force native EventTarget event dispatching on for the React renderer

## Summary:

#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`.

* Fix build_js_types: move abortSignal's required param first

Summary:
#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.

* Update LogBoxInspector snapshots for the safe area insets listener

## Summary:

#59797 added `experimental_onSafeAreaInsetsChange` to the root `logbox_inspector` view, and #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 (#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.
