release: bump version to 0.1.2.0

Stefan's UX-Wunsch: Datei direkt oeffnen ohne Umweg ueber Download.
Plus: in der App fehlte komplett der Per-Row-Download-Button (nur via
Checkbox + Bulk-Download). Beides jetzt gefixt.

App (SettingsScreen.tsx):
  - Neue per-Row-Buttons: 👁 Open + ⬇ Download + 🕒 Versionen + 🗑 Loeschen
  - Open-Pfad nutzt requestId-Praefix 'open-' im file_response-Handler
    → Datei wird nach CachesDirectory geschrieben (kein Storage-Bloat)
    → FileOpener-Native-Module (Intent.ACTION_VIEW mit MIME) oeffnet
      mit dem System-Picker → User waehlt PDF-Viewer / Galerie / Player
  - guessMimeFromName-Helper fuer den Intent damit Android die passende
    App findet
  - Download-Pfad unveraendert ('single-' Praefix), schreibt nach
    DownloadDirectory mit Suffix-Inkrement bei Namens-Konflikt

Diagnostic (server.js + index.html):
  - Neue Route /api/files-view (gleicher Code-Pfad wie files-download,
    aber Content-Disposition:inline + echter MIME-Type statt octet-stream)
  - Browser zeigt PDF / Bilder / Text im neuen Tab statt forcierten Download
  - 👁-Button in jeder File-Row neben ⬇/🕒/🗑
  - Fallback fuer unbekannte MIMEs: octet-stream → Browser bietet Download

Bei beiden Pfaden bleibt der Cache nutzbar: nach App-Open kann der User
die Datei im jeweiligen Viewer behalten; im Browser bleibt sie im Tab.
