feat: add example config for VPS deployment

Add config.example.yaml based on .ship deployment setup:
- gRPC on localhost:50051
- HTTP on localhost:8007 (not 8080)
- Public URL: muxstr.x.bdw.to
- Metrics enabled with dashboard
- Auth/rate-limiting disabled by default

Update .ship/service to use config file instead of individual flags:
- Old: -db -grpc-addr -ws-addr -public-url flags
- New: -config /var/lib/muxstr/config.yaml

Deployment: Copy config.example.yaml to /var/lib/muxstr/config.yaml
