Refactor EnvelopeViewer: Remove PDF viewer init logic

Browse Source 
Simplified the component by removing unnecessary debug output
and redundant comments. Removed the `OnAfterRenderAsync`
method, which previously handled PDF viewer initialization
and related JavaScript calls. This suggests the initialization
logic has been moved elsewhere or is no longer required in
this component.
