chore(medusa): Add transaction on mutation actions (2) (#1855)

**What**
Wrap all actions that require the usage of an atomic phase into a transaction from the handler

**Info**
The following end points have been removed since that they rely on non existing stuff and can't be used and are not used
admin - create-order
admin - delete order metadata
admin - set region metadata
admin - remove region metadata

Fixes CORE-358
