- Change layout to ensure timezone label always visible with shrink-0
- Time text can truncate but timezone label stays intact
- Improves readability in constrained node space
- Fixed convertTimezoneToOffsetStr() that only extracted first digit
* UTC-11 was incorrectly displayed as UTC-1, UTC+10 as UTC+0
* Now correctly extracts full offset using regex and removes leading zeros
- Created reusable TimezoneLabel component with inline mode support
- Added comprehensive unit tests with 100% coverage
- Integrated timezone labels into 3 locations:
* Panel time picker (next to time input)
* Node next execution display
* Panel next 5 executions list
