Simplify loadGlobals for UMD build compatibility

Since the UMD build automatically sets up window.jsPDF, loadGlobals now only needs to:
1. Set up AcroForm aliases (ChoiceField, ListBox, etc.) for backward compatibility
2. Set up window.Canvg from window.canvg.Canvg

Removed the async import promise mechanism entirely - it's no longer needed.

Also added loadGlobals.js back to both karma configs since tests call beforeAll(loadGlobals).
