Subject: [PATCH] Enable Wasm native build and refactor signature layout

Updated EnvelopeGenerator.ReceiverUI.csproj to enable native WebAssembly builds and load all globalization data for improved localization support.

Refactored ReportViewer.razor to enhance layout calculations for the signature section:
- Introduced constants for better readability and maintainability.
- Dynamically adjusted band height and padding to fit content without overlap.
- Updated control positioning and sizing using calculated values.
- Changed font style of the signature label to regular and reordered control additions for clarity.
