Fix CI test failures: PromptManager::add, resource counts, and icon_tool

- PromptManager::add() now properly sets stored.name before storing
- Updated api_basic.cpp to expect 4 resources (includes icon resource)
- Updated api_advanced.cpp to expect 3 resource templates
- Added icon_tool to test mock for client_api_icons tests
