Timezone: Force MySQL Sessions to UTC
Completes the timezone fix from v2.21.2. PHP was already forced to UTC, but MySQL's NOW() and CURRENT_TIMESTAMP were still using the server's local timezone on non-UTC systems. Now sets time_zone = '+00:00' on every MySQL connection so all timestamps are consistent. This should fully resolve time display issues on servers in non-UTC timezones (e.g. Europe/Prague).
New jobs after updating will show correct times. Old timestamps stored before this fix may still be offset.
