feat(ui): two-column settings/details, compact job list, manual run while paused

- Allow manual "Run now" while the scheduler is paused: pause now stops only
  automatic scheduled runs (RunDue), not the user's explicit action. Drop the
  paused guard in Service.RunNow and the UI pause dialog; update tests.
- Cap the details metadata caption width via a new captionValueLayout so a wider
  window feeds extra space to the value column instead of the short caption.
- Reorganize the Settings tab into two columns (Application+Queue / Storage+About)
  with Save spanning the full width; move the Autostart status onto its own line.
- Condense the Jobs list rows with compactVBoxLayout to fit more jobs.
