Update deployment karma configs to use pre-compiled test files

Changed approach to preserve ES module imports in asyncImportHelper:
- asyncImportHelper.ts files contain no type annotations, just ES imports
- Simply copy them to .js during compile-tests (no transpilation needed)
- Removed rollup preprocessing from karma configs
- Karma now loads pre-compiled asyncImportHelper.js files directly

This preserves the native ES module import syntax which allows the browser
to correctly resolve and load the jspdf.es.js module.
