exerciseExplanations.ts: Match and Flashcard explanations translated
into DE, EN, TR, AR, UK, RU, PL, FR, ES, IT, PT, NL, RO, EL, BG,
HR, CS, HU, SV, DA, FI, SK, SL, LT, LV, ET.
Each exercise type gets a parent-facing explanation in the user's
selected language. No more German fallback for unsupported languages.

When a language like PT, FR, IT is selected but has no translation
in exerciseTranslations.ts, the system now falls back to English
instead of German. English is more universally understood.
Applies to: exercise explanations, button labels, instructions.

LanguageSwitcher: Compact dropdown component added to learn/layout.tsx
and parent/layout.tsx — visible on every sub-page (top-right).

language. Parents can switch language mid-session (e.g. when both
parents speak different languages).
