Improve "Save" button visibility or enable Auto-Save for App settings

[mariia-mykhailenko-ethora]

Description:
The current "Save" button in the app settings is not very intuitive/noticeable displaying, and users may assume that changes are saved automatically.

Proposed Solutions:

• Implement auto-save for all changes made in the app settings if it is possible to implement from frontend/backend side.
  Benefit: Users will no longer have to remember to press the Save button manually.

• Make the Save button more prominent and noticeable. Use a more vibrant color (e.g., blue) to highlight the button.

• Add a clear message or tooltip next to the button that reminds users to press Save after every change if previous 2 options are impossible/difficult.

For example, during my first-time use, it was easy to miss the Save button and assume that changes are saved automatically after each update. As a result, after my first change, I was surprised why it wasn't saved and isn't showing now, and I had to make the changes a second time.
