fix: close out remaining German player-facing text across web and API tests

Repo-wide grep sweep (apps/web/src, apps/api/src) for leftover German
content strings missed by Tasks 1-9, mostly in spec fixtures/assertions
that mirror already-translated seed content (monster/item names, POI
titles and action labels, location names/descriptions) plus a few real
source-file gaps:

- inventory-detail-panel.component.ts: STAT_LABELS (Waffenschaden,
  Angriff, Leben, Rüstung) were never translated by Task 6; now match
  the identical English labels already used in inventory-page.component.html.
- app-shell.component.html: aria-label="Spielinhalt" -> "Game content"
  (this file was outside every prior task's file list).
- location-interaction-panel.component.spec.ts: dead NPC-quote fixture
  translated to match the real wounded-scout POI text.

Code comments referencing German source-spec section titles or
not-yet-seeded faction names, and inline calculation-documentation
comments, are left as-is per the source spec's scope (dev-facing
comments may stay German).
