Fix/config dropdown menu mobile view (#7893)

Before:
<img width="534" height="394" alt="grafik" src="https://github.com/user-attachments/assets/63cbf645-2380-448f-9e96-11cf454f9a13" />

1: menu is not right hand side aligned
2: rounded corner (Origine theme specific)

After:
<img width="533" height="359" alt="grafik" src="https://github.com/user-attachments/assets/bfb8fd79-3190-4d40-bba1-ef5fadb81f01" />

Menu is aligned on the right hand side
Sharp corner



Changes proposed in this pull request:

- CSS


How to test the feature manually:

1. small screen for mobile view
2. open config menu right top corner

Negative check:
other dropdown menus should not be touched (f.e. User Queries menu, search, article labels menu)
