Steps to reproduce:

1. Install Zabbix.
2. Open the Frontend on a 1920x1080 monitor with scaling of 125%.
3. Observe the Clock widget.

Result:
On 6.4 and master the default dashboard contains a digital clock, but this clock is not displayed on a standard laptop screen.

125% scaling on a Windows 11 laptop is the default for this resolution and screen size (for reference I use it on my work laptop with 15 inch screen).

The scaling brings the "true" screen width down to 1536px, which is still well over the 1200 minimum supported.

Expected:
I see three possible solutions:
A) (Best) Improve the Digital clock widget so it better handles different sizes and always displays the time.
B) Reorganise the widgets so that the clock widget has more square ratio.
C) Switch back to Analog clock.
