Enhance bootcamp with rich text editor, curriculum management, and video toggle

Phase 1: Rich Text Editor with Code Syntax Highlighting
- Add TipTap CodeBlock extension with lowlight for syntax highlighting
- Support multiple languages (JavaScript, TypeScript, Python, Java, C++, HTML, CSS, JSON)
- Add copy-to-clipboard button on code blocks
- Add line numbers display with CSS
- Replace textarea with RichTextEditor in CurriculumEditor
- Add DOMPurify sanitization in Bootcamp display
- Add dark theme syntax highlighting styles

Phase 2: Admin Curriculum Management Page
- Create dedicated ProductCurriculum page at /admin/products/:id/curriculum
- Three-column layout: Modules (3) | Lessons (5) | Editor (4)
- Full-page UX with drag-and-drop reordering
- Add "Manage Curriculum" button for bootcamp products in AdminProducts
- Breadcrumb navigation back to products

Phase 3: Product-Level Video Source Toggle
- Add youtube_url and embed_code columns to bootcamp_lessons table
- Add video_source and video_source_config columns to products table
- Update ProductCurriculum with separate YouTube URL and Embed Code fields
- Create smart VideoPlayer component in Bootcamp.tsx
- Support YouTube ↔ Embed switching with smart fallback
- Show "Konten tidak tersedia" warning when no video configured
- Maintain backward compatibility with existing video_url field
