feat(infra/nginx): Fixed nginx redirection and fixed dockerfiles

- nginx now use "raw" proxy_pass, where it doesnt supply the $uri since
  if only the host is provided, nginx will handle lots of usecases
- pnpm now uses the lockfile correctly
- Docker: use lockfile in all steps
- Docker: install the necessary packages if building from source is
  needed (better-sqlite3 for example)
