fix: resolve all pre-existing integration test failures (Boy Scout rule)

- ChangePassword/CreateUserWizard: use ID-based selectors instead of
  type-based selectors (.NET 10 InputText rendering change)
- Image/ImageMap: replace external via.placeholder.com URLs with local
  SVG placeholder images to eliminate network dependency
- TreeView/Images: fix image path /img/C#.png -> /img/CSharp.png
- Calendar: filter ASP.NET Core structured log messages from console
  error assertions (timestamp-prefixed messages are not real errors)
- Remove duplicate ImageMap InlineData from EditorControl tests
  (ImageMap is categorized as Navigation Control per team decisions)

Result: 111/111 integration tests passing, 797/797 bUnit tests passing
