feat(ui): condense panels and let the window shrink to 720p

Make the job details and settings views more compact and remove the tall
minimum that prevented resizing the window shorter:

- Lay job metadata out in two columns and stack rows with a negative-gap
  compactVBoxLayout, roughly halving the block height.
- Wrap the settings form in a vertical scroll so it no longer dictates
  the window minimum (AppTabs sizes to the tallest tab), and tighten its
  rows with the same compact layout.
- Shrink the command-output scroll minimum height so the details pane can
  get shorter; long output still scrolls.
- Size the "Selected job activity" panel to exactly maxJobActivityRows
  using widget.List's own content-height formula, so all three rows show
  without a scrollbar regardless of theme or DPI.

Together these drop the minimum window height from ~891px to ~570px.
