fix(Handler): no internal instance cache

See merge request !123

For orders this is not needed. the internal instance cache causes more problems
due to the mix between uuid and id cache. the internal cache on uuid / id was therefore removed.
Orders have the data freshly fetched from the db anyway. therefore unnecessary.
In addition, a wrong order object was repeatedly retrieved when sending mail.

The UX was not optimal as a result. It was not clear that you could scroll and the guest order button was not visible.
For now flex removed and the login buttons are below each other
