fix(admin-ui): translate field labels + responsive header + modal max-h

Issues:
- Field labels (ORBIT/STATUS/COUNTRY/MASS_KG/...) показывались raw'ом потому
  что backend schema не присылает title. Добавил humanize() (snake_case → 'Snake Case')
  + i18n fallback t('field.$key') для известных полей spacecraft/satellite_type/
  ground_station: name, designator, norad_id, status, country, operator, mass_kg,
  mission, orbit, launch_date, decay_date, spectrum_bands, satellite_type_code, etc.
- Modal panel рос в высоту бесконечно (nstart-ui Modal не клампит max-h),
  на iPad портрете форма уходила за viewport. panelClassName=max-h-[calc(100vh-2rem)]
  flex flex-col + bodyClassName=overflow-y-auto flex-1.
- Header в __root: padding/gap responsive (px-4 sm:px-6, py-3 sm:py-4, gap-3 sm:gap-6),
  flex-wrap чтобы LanguageSwitch на узких экранах переносился под навигацию.
- Main container: px-4 sm:px-6 + py-4 sm:py-8.
