Improve zoom control granularity and behavior

Browse Source 
Updated the zoom slider in `EnvelopeViewer.razor` to allow finer adjustments by changing the step size from 25 to 1. Modified `pdf-viewer.js` to enable smoother zooming with 1% increments for `zoomIn` and `zoomOut` methods. Capped zoom levels between 0.5 and 3.0. Enhanced mouse wheel zoom behavior to adjust zoom in 1% steps and notify the .NET side of changes via `OnZoomChanged`. Ensured pages are re-rendered after each zoom adjustment.
