Fix Docker build errors and improve build speed

- Remove non-existent config/production.toml references from Dockerfile
- Remove /etc/qnet directory creation and config path variables
- Change LTO from 'true' to 'thin' for faster compilation
- Add release-fast profile for development builds (no LTO, 16 codegen-units)
- Update Docker build to use release-fast profile for speed
- Fix COPY command paths and startup command arguments
