docs: reorganize documentation structure

- Restructure navigation with clearer hierarchy using "Reference" and "Guides" sections
- Remove deprecated model-specific function calling documentation
- Update all model references to point to centralized Tool Calling documentation
- Rename "Docker Compose" to "Development-time Services" for clarity
- Move "Testing" under Reference section
- Add link to "Awesome Spring AI" community resources
