feat(decks): γ-1 bis γ-8 — AI/CSV-Import, Card-Edit, Pull-Update, Marketplace-Publish + Moderation + PDF

Vervollständigt die Cardecky-Web-Parität für Deck- und Card-Workflows.

γ-1+γ-2 (AI-Deck-Generierung)
- 4-Modi-Picker im DeckEditorView Create-Sheet: Leer/KI/Bild/CSV
- POST /api/v1/decks/generate für Text-Prompt + 10/min Rate-Limit-UI
- POST /api/v1/decks/from-image mit PhotosPicker + PDF-Importer
  (max 5 Files, 10 MiB/Bild, 30 MiB/PDF), Multipart-Body in
  CardsAPI+Generation
- Loading-Overlay mit Task-Cancellation, Error-Mapping für 429/413/502

γ-3 (Card-Edit)
- CardEditorView mit Mode .create(deckId:) / .edit(card:)
- Image-Occlusion + Audio-Front behalten bestehenden Media-Ref, solange
  User nicht ersetzt — MediaCache lädt Bild nach
- Type-Picker im Edit-Modus aus (Server-immutable)
- CardEditorPayload + CardEditorMediaFields als Sub-Views

γ-4 (Pull-Update + Duplicate + Archive)
- POST /marketplace/private/:id/pull-update mit Smart-Merge-Anzeige
- POST /decks/:id/duplicate
- Archive-Toggle im Edit-Modus, Server filtert Liste serverseitig
- DeckSecondaryActions als eigenes Sub-View

γ-6 (CSV-Import)
- RFC-4180-ish Parser (Quote-Escape, Header-Detect, BOM-strip)
- Preview-Liste + sequentielle Card-Inserts mit Live-Progress
- Image-Occlusion/Audio-Front werden geskipped (UI flaggt)

γ-7 (Marketplace-Publish) + Follow-up (Report + Block + Re-Publish)
- MarketplacePublishView mit lazy Author-Setup + Init + Publish 1.0.0
- Re-Publish-Modus: Picker für eigene Marketplace-Decks +
  Auto-Semver-Bump (Minor +1)
- MarketplaceCardConverter (typing → type-in, audio-front → skipped,
  image-occlusion → skipped — Server hat keinen MP-Media-Re-Upload)
- Toolbar-Menü auf PublicDeckView: „Deck melden …" + Author-Blockieren
  (App-Store-Guideline 5.1.1(v))
- ReportDeckSheet mit Reason-Picker (6 Kategorien) + optional Message
- BlockedAuthorsView in Settings mit Swipe-Entblocken

γ-8 (PDF-Export)
- DeckPrintView mit SFSafariViewController auf
  cardecky.mana.how/decks/:id/print — iOS Share-Sheet → PDF speichern

Side-Fixes (mid-stream)
- StudySessionView: Card-Aspect-Ratio springt nicht mehr beim Flip
  (Bottom-Bar in ZStack fixer Höhe)
- RootView: Glass-Pille für „Neues Deck"-Accessory + .guest- und
  .twoFactorRequired-Cases nachgezogen
- DeckListView: Account-Toolbar-Button entfernt (Account-Tab unten
  ist alleinige Anlaufstelle)
