fix(playwright): resolve browser dependencies without sudo & cleanup unused files

- Copy necessary shared libraries (libnss, libasound, libsoftokn, etc.) from docker to libs/ to support headless chromium execution on host
- Update server and crawler configuration to support custom DB_PORT (3307)
- Remove unused databases, lockfiles, standalone helper scripts, and documentation files as requested
