Pull Request Overview

This PR refactors several UI-related files from JavaScript to TypeScript by moving implementations to the __internal directory and converting the original .js files to re-export wrappers. The changes affect core UI components including themes, splitter control, editor factory mixin, filtering utilities, and accessibility helpers.

Key Changes:

• Migrated themes.js, splitter_control.js, ui.editor_factory_mixin.js, filtering.js, and accessibility.js to TypeScript with proper type annotations
• Created wrapper files in original locations that re-export from the new TypeScript implementations
• Updated import paths across consuming files to reference the new internal implementations
• Added TypeScript type definitions for splitter events and options
