Fix notification count and red dot not hidden in title

Fix Title Notifications Feature

Updates the title notifications feature to work with the latest X/Twitter favicon naming convention, changing references from twitter.ico to twitter.3.ico and twitter-pip.2.ico to twitter-pip.3.ico. Also adds the title notifications feature to the dynamic features module so it can be toggled at runtime.

When notifications in title is turned off, the feature now properly restores the original favicon by replacing -pip.3 with .3 in the favicon URL.

I am also calling changeNotificationsTitle function from dynamic.js to handle case where notifications show up while I am already active on Twitter/X
