NethVoice CTI: NethCTI UI container doesn’t update timezone after daylight saving change

[mgarra]

Description:
After the switch from daylight saving time to standard time, the call timestamps shown in the Queue panel and Call history are displayed one hour ahead.

This happens because the NethCTI UI container (nethcti-ui) does not automatically update its timezone when the system time changes.
Querying the container returns the following values:
NUMERIC_TIMEZONE: '+0200',
TIMEZONE: 'Europe/Rome',

while it should be:
NUMERIC_TIMEZONE: '+0100',
TIMEZONE: 'Europe/Rome',

Workaround:
Manually restarting the container updates the timezone correctly:
systemctl --user restart nethcti-ui

Expected behavior:
The nethcti-ui container should automatically reflect the correct timezone after the daylight saving time change, without requiring a manual restart.
