feat: Enhance article generation and outline handling

- Added support for external markdown synchronization in ArticleEditorCanvas.vue.
- Implemented a new function to sync markdown from props, ensuring the editor reflects external changes.
- Introduced a removeOutlineSection function in TemplateWizardView.vue to manage outline sections dynamically.
- Updated UI components to improve user experience, including replacing a-input with a-textarea for better text handling.
- Refactored CSS styles for a cleaner layout and improved responsiveness in TemplateWizardView.vue.
- Enhanced LLM generation requests to include response format options in ark.go and client.go.
- Updated template assist logic to enforce structured outline outputs in template_assist.go.
- Added tests for outline result decoding and prompt generation to ensure robustness.
- Created migration scripts to update prompt templates with new writing requirements for top X articles.
