fix(timezone): fix UTC offset display bug and add timezone labels
- 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
