Made demo apps programmatic SEO-ready

• Updated the schema and database to store title, subtitle, and description for each generation.

• Adjusted the generations page ([id]/page.tsx) to dynamically fetch and display this metadata.

• Meta tags are now generated based on user-created content for better SEO optimization.

• Removed unnecessary hooks and routes (getAIresponse.ts and fetch/route.ts), streamlining the backend logic.

• Suggested strategy: Use internal backlinking for user-generated content pages to improve search engine crawlability.
