refactor(log): replace utility/log with imp/log in shm.cpp

- Replace include "libipc/utility/log.h" with "libipc/imp/log.h"
- Replace ipc::error() calls with LIBIPC_LOG() + log.error()
- Use type-safe streaming interface instead of printf-style formatting
- Remove manual newline characters from log messages
