fix #249 header 2 (#425)

* Header updates
* More pixel alignment for nav
* Update unit test snapshots
I removed a stray `,` from `testHelpers.tsx` which changed the output of several snapshots.
* Fixes from PR review
* Forgot to update snapshots after merge with main
* Removed unused (and outdated) timeline page
* Updated some translation descriptions.
