feat: Update chat creation UI and enhance knowledge post-processing logic

- Modified the chat creation component to improve layout and responsiveness by adjusting the dialogue answers section.
- Refined the logic in the KnowledgePostProcessService to conditionally spawn wiki ingest tasks based on wiki configuration settings, enhancing task management.
- Added migration scripts for creating and dropping the `wiki_page_issues` table, facilitating better issue tracking within the wiki system.

These changes enhance the user interface for chat creation and improve the backend processing of knowledge base tasks, contributing to a more efficient and user-friendly experience.
