Fix Qt6.11 compatibility and complete GUI build

Browse Source 
- Updated build.bat to detect Qt6.11.1 and Qt6.10.2 installations
- Added find-qt.bat helper script to locate Qt6 on system
- Fixed CMakeLists.txt to remove app.rc requirement
- Fixed QDateTime::currentTime() -> currentDateTime() for Qt6
- Added missing #include <QCloseEvent> in MainWindow.cpp
- Fixed QFileInfo includes in ServerProcess.cpp
- Replaced complex QOverload signal connections with SIGNAL/SLOT macros
- Fixed emit error() ambiguity by using this->error()
- Successfully builds CommonwealthOnlineHost.exe with Qt6.11.1

Build was blocked because:
1. CMake couldn't find Qt6 at standard locations
2. Qt6.11.1 uses different signal/slot APIs than documented
3. Missing header includes for Qt6 compatibility

Solutions applied:
- Auto-detection now checks C:\Qt\6.11.1 and 6.10.2
- Simplified connections to use SIGNAL/SLOT string-based syntax
- All missing headers now included
- Added find-qt.bat for manual Qt discovery

Executable now builds successfully!
