Translates the remaining German static copy in the layout/shared components
per the design doc glossary: top-bar (World Renown, Silver, loading text),
side-navigation (nav labels and aria-labels), context-panel (area info,
safety/hunt facts, encounters), game-footer (connection status, Ashen Fields),
and reputation-display (aria-label, highest-rank text). Also fixes stale
German rank-label fixtures in reputation-display.component.spec.ts flagged
by Task 2's reviewer, and updates app.spec.ts assertions that exercised the
now-translated side-navigation/top-bar output via the app shell.
