Summary:
Migrates the remaining meaningful coverage from `TextInput-test.js` (Jest with snapshots) over to `TextInput-itest.js` (Fantom) so we can rely on a single test file that exercises the real renderer instead of a heavily-mocked one.
Changes in `TextInput-itest.js`:
- Add a `focus()` test verifying that focusing a `TextInput` unfocuses any previously focused one (mirrors Jest's "should unfocus when other TextInput is focused").
- Add a top-level `has the correct displayName` test.
- Add a new set of `props` describes that assert the props from the original Jest snapshot tests reach the mounting layer via `getRenderedOutput({props: [...]}).toJSX()`:
- `id and nativeID`: `id` → `nativeID` mapping, `nativeID` pass-through, and `id` precedence over `nativeID`.
- `testID`: pass-through.
- `aria-label and accessibilityLabel`: `aria-label` → `accessibilityLabel` mapping and `accessibilityLabel` pass-through.
- `aria-* and accessibilityState`: `aria-busy/checked/disabled/expanded/selected` mapped into `accessibilityState`.
- `accessibilityRole`: pass-through.
- `style`: `backgroundColor` propagated as a native color value.
Tests intentionally NOT ported:
- Inherited `HostInstance` method presence checks (`focus`, `blur`, `setNativeProps`, `measure`, `measureInWindow`, `measureLayout`): they are guaranteed by Flow typing on `ReactNativeElement`, exercised in `ReactNativeElement-itest.js`, and Flow's `method-unbinding` rule prevents the simple `toBeInstanceOf(Function)` check without `$FlowFixMe` (which is forbidden by project rules).
- `focus() should not do anything if the TextInput is not editable`: `TextInputState.focusTextInput` reads `textField.currentProps?.editable`, but in the new architecture `currentProps` is not exposed on the public `ReactNativeElement` instance, so the check is effectively bypassed. The Jest test only passed by monkey-patching `currentProps`. Documenting this as expected behavior in Fantom would mask a real bug.
- `should give precedence to textContentType when set`: `textContentType` is iOS-only and Fantom defaults to Android (`AndroidTextInput`).
Files removed:

- `Libraries/Components/TextInput/__tests__/__snapshots__/TextInput-test.js.snap`

Summary: All Meta apps have migrated to Fabric, so we no longer need to support Paper in the renderer infrastructure. This commit simplifies: - RendererImplementation.js: Rewritten to only use Fabric renderer - RendererProxy.fb.js: Removed Paper-related exports - RendererProxy.js: Updated comment to reflect Fabric variants (profiling vs production) - FabricRendererImplementationWithProfiling.js: Removed Paper shims - Jest mock RendererProxy.js: Removed Paper exports Differential Revision: D101353113
