[Improvement]: Save functionality

[mcop1]

Improvement description

When clicking on the save button, every perspective or custom view is saved to the configured write target. Even if nothing has changed at all.

1. Save only changed perspectives or custom views to the configured write target
2. Adapt the GUI to reflect other configuration GUIs in pimcore, like Datahub / GraphQL
   2.1 e.g. add Tabs
