Refactor presentation components following coding guidelines

## Major Refactoring
- Broke down large components into focused, reusable pieces
- Reduced NewPresentationPage.tsx from 238 to 172 lines
- Reduced PresentationEditor.tsx from 457 to 261 lines
- Eliminated functions exceeding 50-line guideline

## New Reusable Components
- PresentationDetailsForm: Form inputs for title/description
- AspectRatioSelector: Aspect ratio selection grid
- ThemeSelectionSection: Theme selection wrapper
- CreationActions: Action buttons and selected theme info
- EmptyPresentationState: Empty presentation state display
- SlidesSidebar: Complete sidebar with slides list
- SlideThumbnail: Individual slide thumbnail with actions
- LoadingState: Reusable loading component with spinner
- ErrorState: Reusable error display with retry/back actions

## New Hooks
- useSlideOperations: Custom hook for slide duplicate/delete logic

## Code Quality Improvements
- Replaced browser alert() calls with AlertDialog component
- Updated imports to use direct .tsx extensions per IMPORT_STANDARDS.md
- Eliminated browser confirm() calls in favor of ConfirmDialog system
- Consolidated duplicate loading/error state patterns
- Improved type safety throughout

## Benefits
- Better maintainability through component separation
- Consistent UX with shared UI components
- Code reuse across presentation components
- Compliance with 200-line file guideline
