Fix loadGlobals to use correct UMD global name

The UMD build exports to window.jspdf (lowercase), not window.jsPDF.
Updated loadGlobals to:
1. Read from window.jspdf (the UMD export)
2. Set up window.jsPDF (capitalized, for backward compatibility)
3. Set up all other globals from window.jspdf

This matches the actual UMD pattern:
  (global.jspdf = {}, factory(global.jspdf))

Where jspdf.jsPDF is the constructor.
