i18n(articles): translate DetailView via $_() — page title, meta-row, tag picker, floating reader toolbar

- <title> with {title} interpolation, untitled fallback
- Loading + not-found states, "Zurück zur Liste" button
- Meta-row: "{n} min" reading-time + "{n} Wörter" word-count via interpolation
- TagField: addLabel + placeholder
- Floating toolbar: aria-label
- Nav group: back button (aria + tip)
- Type group: A−/A+ font-size buttons (aria + tip), Serif/Sans toggles, 3 theme swatches (Heller/Sepia/Dunkler Modus) — aria + tip mirror
- Action group: read/unread toggle, favorite toggle, archive, open-original link, delete — all with $_() conditional aria + tip pairs
- "Artikel wirklich löschen?" confirm

Baselines: hardcoded 1119 → 1112 (7 cleared, of 9 — 2 strings carry through identifiers in helpers); missing-keys baseline unchanged.
