Fix asyncImportHelper import paths for compiled location

The asyncImportHelper files are compiled to test/compiled/*/asyncImportHelper.js,
so the relative paths need to account for the compiled directory depth:

- Unit tests: test/compiled/unit/ needs ../../../dist/jspdf.es.js (3 levels up)
- ESM tests: test/compiled/deployment/esm/ needs ../../../../dist/jspdf.es.js (4 levels up)

These paths resolve correctly to /base/dist/jspdf.es.js when served by Karma.
