refactor(render): cleanup consolidate triplicated stencil implementations into shared utility

- Create unified StencilUtils.kt with all stencil functionality
- Migrate 6 files from Stencil/StencilUtil to StencilUtils
- Remove duplicate Stencil.java and StencilUtil.java
- Add deprecation warnings to RenderUtils delegates
- Reduce codebase by 191 lines of duplicate code"
