Note

Medium Risk
Updates the consent automation bundle used on real pages; upstream rule changes can alter CMP detection/opt-out behavior across sites even though the change is largely a version bump.

Overview
Bumps @duckduckgo/autoconsent from 14.71.x/14.72.0 to 14.74.0 and refreshes package-lock.json accordingly.

Regenerates the shipped autoconsent-bundle.js to the new upstream version, including updated CMP detection/interaction logic and minor robustness tweaks in button text handling and Sourcepoint opt-out flow.
