Fixed replacement staging stalls

- Concurrent replacement requests report busy before waiting for the manager lock
- Replacement staging reports localized phases and elapsed time
- Player progress messages use entity scheduling
- Pack copies flush completed files after traversal
- Replacement admission and progress tests cover scheduling and cleanup
- Language editor tests use a local catalog response
