**Patch Notes**
Updated the Guild Panel `Statistics` page.
- Added city-based production statistics for the selected good.
- The city list now shows city name, population, total production building count, and daily production.
- Added a large good-selection popup opened through the change-good button.
- When the popup is open, pressing `Esc` closes only the popup; the Guild Panel stays open.
- Mouse wheel scrolling over the list no longer moves or zooms the camera.
- Adjusted city-name positioning, icon alignment, font size, scrollbar, and popup layout.
- Aligned `ImgOptions` icons with the production-building and daily-production icons.
- Split oversized Guild statistics/trader classes into partial files; no 300+ line `.cs` classes remain.
- Build verification passed: `dotnet build HansaForever.slnx`.
