Menubar is partially hidden or overlapped in Merkuro Contact

SUMMARY
Menubar is partially hidden or overlapped in Merkuro Contact

DESCRIPTION
When opening Merkuro Contact, the top menubar (File, Settings, Help) appears partially hidden or overlapped by the window header. This makes it difficult to interact with the menu, especially on Wayland sessions or lower screen resolutions.

STEPS TO REPRODUCE
1. Launch Merkuro Contact
2. Observe the top section of the window, especially the menubar
3. Try to click the "File" or "Settings" menu

OBSERVED RESULT
The menubar appears overlapped by the window titlebar or header, and is not fully visible or clickable.

EXPECTED RESULT
The menubar should be fully visible and interactable below the window title area.
