Module menu: customisable order of menu items

[01es]

Description

Prerequisite: #2067

Similar to #2044, it would be nice to support custom ordering of the Module menu items. Group items should be moving all its sub-items. It should not be possible to move a menu item outside of its group.

Changes to the order of Module menu items should be persisted locally.

Expected outcome

Ability for users to order Module menu items to fit their needs.
