fix(android): configure embedded views on New Architecture

[thomson-t]

Background

• On React Native's New Architecture, RoktEmbeddedViewManager implements the codegen-generated interface but did not return its generated delegate from getDelegate().
• React Native therefore logged a ReactNoCrashSoftException whenever it created RoktNativeWidget, and placeholderName was not routed through codegen property dispatch.

What Has Changed

• Instantiated RoktNativeWidgetManagerDelegate in the New Architecture view manager and returned it from getDelegate().
• Removed the redundant @ReactProp annotation because the generated delegate now owns placeholderName dispatch.
• Kept the Paper implementation, event handling, and public JavaScript API unchanged.

Screenshots/Video

• N/A — no visual changes. Verified by launching the RN 0.81.5 sample under Fabric and confirming the RoktNativeWidget delegate soft exception no longer appears in logcat.

Checklist

• I have performed a self-review of my own code.
• I have made corresponding changes to the documentation.
• I have added tests that prove my fix is effective or that my feature works.
• I have tested this locally.

Additional Notes

• trunk check --ci, Widget lint, TypeScript build, Expo plugin build, package creation, and the Android New Architecture build all pass.
• The sample repository has no matching Jest tests or dedicated Android view-manager test harness, so this regression is covered by codegen compilation and emulator runtime validation.
• No documentation or changelog update is required because the public API and integration steps are unchanged.
