• Updated ROADMAP.md to clarify the status of features in the v1.1.0 and v1.2.0 releases, marking several v1.1.0 features as completed and moving "Enhanced Status Monitoring" to v1.2.0 for further improvements.

Blazor component improvements:

• Added the @namespace LANdalf.UI.Components directive to DeviceHistoryDialog.razor to explicitly set its namespace, improving code organization and maintainability.
