- Update authentication link to point to correct documentation endpoint
- Standardize model naming convention (remove '-main' suffix)
- Expand cost management section to include analytics visualization
- Add gateway metrics image to illustrate analytics capabilities
- Reorganize sections for better content flow and readability
- Streamline troubleshooting content for conciseness

These changes improve accuracy, visual appeal, and user experience
while maintaining comprehensive integration guidance.
