🔐 security: Disable user-input eval in pdfjs-dist usage.

By default, pdfjs-dist optimizes some path resolution logic by compiling
a JavaScript function on the fly. The function is built using string
concatenation and no effort is made at sanitizing the parts it is
built from. These parts could contain user-input which leads to a code
injection vulnerability. This commit disables this default behavior.
An alternative is to upgrade pdfjs-dist to v4.2.67 or later.

Not sure if this will break anything and/or will make certain things
slower.
