[WIP] Replace defineEditorAttributes with new attribute system

[Copilot]

Migration Plan: Replace defineEditorAttribute with Constructor-based Attributes

This PR migrates from the old defineEditorAttribute pattern to the new constructor-based attribute system.

Understanding the Migration Pattern

Old Pattern (defineEditorAttribute):

• Attributes were set dynamically in defineEditorAttribute() method
• Called at runtime when UI is configured
• Separation between field initialization and UI configuration

New Pattern (Constructor):

• Attributes configured during field initialization in constructor
• Uses field.uiCapability()->setUiEditorTypeName(), setUiLabelPosition(), etc.
• Helper methods available: PdmUiNativeCheckBoxEditor::configureFieldForEditor(), etc.

Migration Checklist

• Understand the migration pattern and examples
• Identify all files with defineEditorAttribute (298 files found)
• Start with simple examples to validate the approach
• Migrate Application preferences files (RiaPreferences*.cpp)
• Migrate ProjectDataModel files systematically
• Remove defineEditorAttribute method declarations and implementations
• Verify no regressions in UI behavior
• Document the migration for future reference

Files to Process

• Total files with defineEditorAttribute: 298
• Starting with: Application preferences classes
• Then: ProjectDataModel classes systematically
