fix: Docker port mismatch — server now binds 3000/3001 as documented

The sensing server defaults to HTTP :8080 and WS :8765, but Docker
exposes :3000/:3001. Added --http-port 3000 --ws-port 3001 to CMD
in both Dockerfile.rust and docker-compose.yml.

Verified both images build and run:
- Rust: 133 MB, all endpoints responding (health, sensing/latest,
  vital-signs, pose/current, info, model/info, UI)
- Python: 569 MB, all packages importable (websockets, fastapi)
- RVF file: 13 KB, valid RVFS magic bytes

Also fixed README Quick Start endpoints to match actual routes:
- /api/v1/health → /health
- /api/v1/sensing → /api/v1/sensing/latest
- Added /api/v1/pose/current and /api/v1/info examples
- Added port mapping note for Docker vs local dev
