Franck Nijhof ce5640d13a Fix time zone picker data gaps (UTC and Asia/Sakhalin) (#52754) ...

* Add UTC time zone to the time zone picker

The time zone list is built from google-timezones-json, which is missing
the bare "UTC" and "Etc/UTC" zones. Both are valid IANA identifiers and a
common server default, so an instance configured to UTC showed up as an
unknown time zone in the settings.

Add the two zones to the picker options, guarded against duplicates in
case the source list starts including them.

* Accept UTC time zone in the clock card config

The clock card validated its time_zone against the raw timezone list, so
it rejected UTC even though the picker now offers it. Validate against the
shared timezone options instead, keeping a single source.

* Correct the invalid Asia/Sakhalin time zone id

google-timezones-json ships Asia/Yuzhno-Sakhalinsk, which is not a valid
IANA identifier, so selecting it failed backend validation. Map it to the
correct Asia/Sakhalin id.
