Fix code review findings for Story 3.3: Preset Import & Export

Browse Source 
Security & Quality Improvements:
- Fix XSS vulnerabilities in PresetImportDialog, PresetExportDialog, and templates
- Add resource leak protection in downloadExportFile() with try/finally
- Fix encapsulation violation by using public API instead of _presetsCache
- Add rollback mechanism for partial failures in replace mode
- Add preset name validation (length, characters, empty check)
- Add duplicate name detection within import files
- Add file size validation (5MB limit) and type validation
- Fix event listener leaks with proper cleanup in _onRender/_onClose
- Add constructor parameter validation for all dialogs

Acceptance Criteria Compliance:
- Fix AC-2: Export filename now uses world name (via parent.name)
- Fix AC-6: Error message matches spec exactly ('Import failed: invalid JSON format')
- Fix AC-8: Merge/Replace messages match spec format

Code Quality:
- Add shared HTML escaping utilities (src/utils/html.js)
- Consolidate duplicate localization strings (removed 28 duplicates from SCRYING_POOL)
- Use SCENE_PRESET_VERSION constant instead of hardcoded 1
- Handle null options in importPresets()
- Graceful handling of skipValidation with invalid data

Test Results: 679 passed, 3 failed (pre-existing in DirectorsBoard)
