Context

Previously, Hyprlock hid the placeholder text after a short timeout, making it unclear which keyboard layout was active before typing a password.
This caused authentication mistakes and unnecessary retries for users with multiple layouts (e.g., DE/EN/HR...).
The update ensures the layout is always visible, improving consistency and usability.

How Has This Been Tested?

• Tested on Fedora Linux/Based Distro.
