Masthead Revision

[guerler]

The goal of this PR is to achieve consistency and reduce redundancy in the Masthead and align its functionality with the Activity Bar. The PR also contains improvements to the Activity Bar and Masthead as recently discussed during the UX team meeting.

1. @mvdbeek suggested that hidden and less frequently used activities should still be readily accessible. To account for that, the Settings activity has been replaced with a More activity. Users may still use this activity to add or remove items from the activity bar. Additionally, now users may also directly navigate to any activity using this panel.

2. @davelopez suggested that the username should be visible to the user and that accessing user preferences should remain in the masthead dropdown. This idea has been implemented, the username has been added to the masthead, user preferences and logout are accessible through the user tab.

Resolves #17476, #17109, #17513.
