Fix sidebar configuration: remove legacy endpoint references

- Updated sidebars.ts to only include new Bearer token API documentation
- Removed references to deleted legacy endpoints (stt, translate, tts, voice, lipsync, live-portrait)
- Fixed Docusaurus build error by aligning sidebar with actual documentation structure
- Sidebar now includes: video-generation, api-keys, billing
