webui: convert sketch-todo-panel to SketchTailwindElement with comprehensive test suite

Convert sketch-todo-panel component from LitElement with CSS-in-JS to SketchTailwindElement
inheritance using Tailwind utility classes, and add complete testing infrastructure with
TypeScript demo module and comprehensive test coverage.

Component Conversion:
- Replace LitElement with SketchTailwindElement inheritance to disable shadow DOM
- Remove 200+ lines of CSS-in-JS styles in favor of Tailwind utility classes
- Convert all styling to Tailwind class compositions while maintaining visual parity
- Add inline fadeIn animation using <style> tag following established patterns
- Preserve all existing functionality: todo rendering, comment system, loading states

CSS-to-Tailwind Mapping:
- Main container: flex flex-col h-full bg-transparent overflow-hidden
- Header section: py-2 px-3 border-b border-gray-300 bg-gray-100 font-semibold text-xs
- Content area: flex-1 overflow-y-auto p-2 pb-5 text-xs leading-relaxed min-h-0
- Todo items: flex items-start p-2 mb-1.5 rounded bg-white border border-gray-300 gap-2
- Loading state: animate-spin with proper Tailwind spinner classes
- Comment modal: fixed inset-0 bg-black bg-opacity-30 z-[10000] with centered content
- Status icons: ✅ completed, 🦉 in-progress, ⚪ queued with proper sizing
- Interactive buttons: hover states and transitions using Tailwind utility classes

Test Infrastructure:
- Create sketch-todo-panel.test.ts with 14 comprehensive test cases
- Test initialization, visibility, state management (loading/error/empty states)
- Test todo rendering: status icons, task descriptions, progress counts
- Test comment system: button visibility, modal interactions, event dispatch
- Test error handling: invalid JSON parsing, empty content scenarios
- Test Tailwind integration: proper class usage, shadow DOM disabled
- Test scrollable interface: large todo lists render and scroll correctly
- Use @sand4rt/experimental-ct-web framework following established patterns
- Include helper functions for mock TodoItem creation and test utilities

Demo Module Integration:
- Create sketch-todo-panel.demo.ts following established TypeScript demo pattern
- Add comprehensive demo scenarios: basic usage, loading/error/empty states
- Include large scrollable list demonstration with multiple todo items
- Add interactive comment functionality testing with event logging
- Add sketch-todo-panel to demo-runner.ts knownComponents registry
- Demonstrate all component states and user interactions comprehensively

TypeScript Compatibility:
- Fix property access for private @state() properties using component.evaluate()
- Use type assertions for addEventListener/removeEventListener on SketchTailwindElement
- Address interface compatibility issues with proper TypeScript patterns
- Remove unused imports and helper functions to maintain ESLint compliance
- Follow established patterns from other SketchTailwindElement components

Files Modified:
- sketch/webui/src/web-components/sketch-todo-panel.ts: TailwindElement conversion with complete CSS removal
- sketch/webui/src/web-components/demo/demo-framework/demo-runner.ts: Added component to registry

Files Added:
- sketch/webui/src/web-components/sketch-todo-panel.test.ts: Comprehensive test suite with 14 test cases
- sketch/webui/src/web-components/demo/sketch-todo-panel.demo.ts: Interactive TypeScript demo module

The conversion maintains complete functional parity while enabling consistent
Tailwind-based styling, comprehensive test coverage, and improved development
experience through integrated demo infrastructure.
