fix: show all enabled panels on chat lobby instead of only templates

* feat: update about page examples with new diagrams

Replace old cloud architecture and cat examples with ResNet50, RAG,
Authentication, Agile Scrum, and Open Innovation diagrams.
Update all three language versions (EN, CN, JA) for consistency.

* fix: correct ResNet50 prompt text and keep prompts in English

Update the ResNet50 example prompt to match the actual diagram.
Keep all prompt texts in English across CN and JA about pages
since prompts are what users type into the AI.

* docs: update README examples to match about page

Replace GCP, AWS, Azure examples with ResNet50, RAG, Auth,
Agile Scrum, and Open Innovation. Keep Animated Transformer
and Cat Sketch. Keep prompts in English across all versions.

* docs: remove ResNet50 and Agile Scrum examples from READMEs
