feat(study): Typing-Karten + Levenshtein-Match-Logik

CardRenderer für typing ist nicht mehr Placeholder. Web-Vorbild:
TypingView.svelte + cards-domain/typing.ts.

Typing.swift (Sources/Core/Domain/):
- check(input:answer:aliases:) → TypingMatch (correct/close/wrong)
- Normalisierung: trim + lowercase + NFD-Decomp + Combining-Marks
  strippen (Diakritika: ä → a)
- Aliases-Support (Komma-getrennt aus card.fields["aliases"])
- Levenshtein-Threshold max(1, floor(len * 0.2)) → "close"

TypingCardView (Features/Study/):
- TextField mit Auto-Focus 0.15s nach onAppear, Return = Submit
- Submit-Button mit Return-Symbol + primary background
- Nach Submit: Badge (✓ Richtig / ≈ Fast / ✗ Falsch) + User-
  Eingabe in „…" Quotes + Divider + erwartete Antwort
- Haptic-Feedback: heavy bei correct, light bei close/wrong
- Reset on card.id change

TypingTests: 8 Tests für check() — exact, case+whitespace,
NFD-Umlauts, aliases, Levenshtein-close (Berln → Berlin),
empty-input, sowie Levenshtein-Helper-Sanity.

Build 8 → 9. 43 Tests grün (war 35).
