fix(example): forward cell refs and clean up animation resources

[OskarEichler]

Fixes

Forward custom renderer refs, reset/stop cell animations on recycle/unmount, preserve hidden opacity and inversion transforms, bound List refresh work and cancel Carousel resize callbacks. Move recycling-image opacity changes out of render and forward the original onLoad event.

Compatibility / observable changes

Example-only changes. Custom cells retain measurement refs and hidden/inverted styles. No exported library API change; no claim of isolating stale image-loader events.

Verification

• Consumer verification: the combined fixes were packaged on the unchanged npm 2.3.2 runtime baseline and checked with React Native 0.87.1 / React 19.2.3. Immutable install, lint, both Android Debug variants, both unsigned iOS Simulator variants, four Metro bundles, 13 web targets and four browser-extension builds pass. All 298 installed non-metadata package files match the reviewed artifact byte-for-byte.
• Independent patch applied to 435b5141df4960ebbbc0b93264db3f5a4b23fffd: all 187 existing tests (14 suites), library TypeScript build and changed-file ESLint pass.
• One-off actual-source regression diagnostics pass:
  • custom animated renderer 0 forwards refs and cancels animations
  • custom animated renderer 1 forwards refs and cancels animations
  • list refresh is bounded and cancelled on unmount
  • iOS recycling image forwards onLoad event and resets opacity
• The combined review workspace passes Android Debug, unsigned iOS Simulator Debug/Release, both production Metro bundles, web production export, Docusaurus/Jekyll builds and all 24 existing iOS Detox tests (10 suites). The contacts comparison was rerun after its final change. These combined-workspace results are not a claim that every device/platform was tested independently for this PR.
• No checked-in tests, reference screenshots, dependency versions or native SDK versions were changed.

Reviewers’ hat-rack 🎩

• Check the stated compatibility behavior and reproduce the relevant cases above.
• Run the existing test/type/lint commands and exercise the affected example or list behavior on your supported device matrix.

Physical-device behavior, Android Detox, assistive-technology conformance and release signing were not verified. No app deployment is part of this PR.
