Fixed a number of minor qol issues (merge from minor_qol_fixes):

- Added a small notification badge on new snips in queue. Not synced
between devices yet but shows if you haven't seen the snippet yet. Is
set to seen once you hover over the snip or select it the first time.
All snips are set to seen on page reload. This should at the moment only
be used as an indicator for new snips in the queue.

- Minor inconveniences if the user tries to logout. Previously logout
was only possible from the fontpage, now it is possible from the account
page too and the branding (icon on the top right) redirects to the
account page.

- Reversed order of snip queue items, now the newest is at the bottom to
mirror the behavior of the page tab (by public demand).

- Scrollbar in the sidebar is now on the right side (by public demand).
