Cause:
* A configuration control can reject an incompatible configuration and return null.
* ComponentsManagerDlg accessed the rejected configuration without validation, causing a NullReferenceException and closing TBF.
* The standard MessageBox was difficult to read and did not provide convenient access to technical details.
Solution:
1. Added configuration validation
* Validates the configuration returned by the component control.
* Logs the rejected control and configuration types.
* Cancels the add operation without terminating TBF.
2. Added a reusable error details dialog
* Displays a clear error summary and structured technical details.
* Allows the diagnostic text to be selected and copied.
* Added Copy and Close actions and registered the new form in TBF.csproj.
3. Increased revision
* Updated revision to 3.9.3145.109.
