 internal: fix missing null check for g_IPCSocket in onRepeatTimer (#368) 
CWallpaperTarget::onRepeatTimer() calls IPC::g_IPCSocket->onWallpaperChanged()
without checking if g_IPCSocket is valid. When IPC is disabled (ipc=0) or
not initialized, g_IPCSocket is nullptr, causing a SIGSEGV.

Stack trace from coredump:
  #0  __normal_iterator constructor (this->m_statusObjects at 0x60)
  #1  IPC::CSocket::onWallpaperChanged (this=0x0)
  #2  CWallpaperTarget::onRepeatTimer

GDB confirms this=0x0 in onWallpaperChanged, meaning g_IPCSocket.get()
returned nullptr when dereferenced.

Fix: add a null guard matching the pattern already used in registerOutput()
and elsewhere in the codebase.
