Fix: Finanzen-Tab bleibt bei 'Lade...' hängen (v1.8.21)

fEur/fKwh waren lokale Funktionen in renderEnergy() — loadFinance()
konnte sie nicht aufrufen (ReferenceError außerhalb des Scopes).
Beide Funktionen in den globalen Scope verschoben, lokale Kopien entfernt.
loadFinance() Rendering-Block in try/catch gewrappt.
