[Bug Report] UI: prefs: coredump pressing +/- on server keepalive timeout

[UffeJakobsen]

UI: prefs: coredump pressing +/- on server keepalive timeout

Seen with latest master (c15899b) on Archlinux

Going into Preferences / Server / Internal - pressing either "+" or "-" on the new setting 'keepalive timeout' causes UI to coredump

Traceback (most recent call last):
  File "/usr/lib/python3.13/site-packages/opensnitch/dialogs/preferences/signals.py", line 22, in <lambda>
