refactor: optimize string operations and improve code clarity

Browse Source 
- Avoid redundant substr() calls in packet parsing hot-path (TServer.cpp)
  The previous code called substr(3) twice per packet, creating
  unnecessary temporary strings. Now stores the result once.

- Replace .size() == 0 with .empty() for idiomatic C++
  (TConsole.cpp, TLuaEngine.cpp)
