Add anchor tags to drop-down menu and user page

Changes proposed in this pull request:

• Add anchor elements to drop-down menu when logged in
• Add anchor elements to tabs on user page

How to test:

• docker compose down --volumes && docker compose build --parallel && docker compose up --scale data-generation=1
• Log in, test out the items in the drop-down menu of your avatar. Clicking them normally should not trigger a full page reload. You can also right click them or open them in a new tab with the middle mouse button
• Go to e.g. http://localhost/user/software, test the same for the different tabs
• Check that the styling (especially on mouse hover) is ok

PR Checklist:

• [ ] Increase version numbers in docker-compose.yml
• [ ] Link to a GitHub issue
• [ ] Update documentation
• [ ] Tests
