feat(explorer): add SVD axis themes and unique-motion deduplication

- Regenerated top_svd_top_motions.json for window=2025 with strict
  cross-axis deduplication: 100 unique motions across 10 axes (10 per
  axis, zero overlap), sorted by absolute SVD score
- Added SVD_THEMES dict to build_svd_components_tab with Dutch-language
  theme label and political-polarisation explanation for each of the 10
  axes (e.g. 'Confessioneel-conservatief vs. seculier-progressief')
- Selectbox now shows 'As N — <theme>' instead of bare component number
- Each selected axis shows an info banner with the full explanation
- Motion list buttons show ▲/▼ to indicate positive/negative SVD loading
- Translated UI strings to Dutch for consistency
