test(country-map): controlPanel test (10 cases)

Completes the test trio (transformProps + buildQuery + controlPanel).
Verifies:

- All 9 new controls (worldview / admin_level / country / region_set /
  composite / region_includes / region_excludes / show_flying_islands /
  name_language) are present in the panel
- Worldview defaults to 'ukr' (Superset's editorial choice)
- show_flying_islands defaults to true
- name_language defaults to 'en'
- admin_level offers exactly the 3 expected codes
- Country selector visibility hides on Admin 0 OR when composite set
- Region-set selector only visible when admin_level === 'aggregated'
- Region-set choices key off the selected country (TUR → nuts_1,
  FRA → regions, USA → empty)
- Composite selector exposes france_overseas

These tests would fail loudly if anyone refactored the visibility
predicates or accidentally removed/renamed a control.
