fix(pdfWorker): use legacy worker build for browser compatibility

The standard pdfjs-dist worker build uses Uint8Array.prototype.toHex
natively, which requires Chrome 128+ and Firefox 132+. The legacy build
includes a polyfill for this method, making it compatible with the
browser targets declared in the project (Chrome 116+, Firefox ESR).
