feat: narrower margins on landscape topology pages

- Landscape pages use 7 mm side margins (PDF) / 0.7 cm (Word) and
  compact headings, so the topology gets about 28 cm of width.
- Portrait pages after a landscape page restore their original margins.
- The topology PNG is cropped to its content, removing the blank border.

Bump version to 0.6.1.
