Fix: "Validate all forms" crashes when no project is active

[bero]

Bug

The Bold menu action "Validate all forms" crashes with an access violation when:

• No project is open in the IDE
• A project group exists but has no active project

Root cause

In BoldComponentValidatorIDE.pas, the method ValidateIOTAModules accesses Project.FileName and Project.GetModuleCount without checking if Project is assigned:

Project := ProjectGroup.ActiveProject;
BoldLog.LogFmt(sDefaultProject, [Project.FileName]); // Crash if nil

Fix

Added nil checks before accessing Project properties:

1. Check Assigned(Project) after ProjectGroup.ActiveProject before logging
2. Wrap the project module iteration in if Assigned(Project) with a fallback log message
