Reorganize interface: streamline assistant configuration and improve preview feedback

- Remove Tool Settings accordion for cleaner interface
- Move web search under Research Template with auto-enable
- Group Document RAG and URL Grounding in Assistant Configuration
- Position features logically: Research → Web Search → Document RAG → URL Grounding → Examples
- Add success notification for preview generation
- Update max tokens default to 1500
