fix: Security Issues + Bug Fixes

SECURITY FIXES:
- SEC-1: Debug-Endpoints (/api/debug/*) entfernt - waren ohne Auth zugänglich
- SEC-2: debugCode aus 2FA API-Responses entfernt (nur noch console.log in dev)
- SEC-3: Session Secret Validierung - Server startet nicht ohne SECRET in production
- SEC-4: 2FA if(true) bypass entfernt - 2FA-Flow funktioniert jetzt korrekt
- SEC-5: Auth-Checks auf 10 Endpoints hinzugefügt (labels, notes, goals, rewards)

BUG FIXES:
- DUP-1: Doppelte DELETE /api/tasks/:id Route entfernt
- DUP-2: Doppelter deleteLabel() Aufruf entfernt
- DEAD-4: PATCH /api/goals/:id nutzt jetzt updateGoal() statt updateTask()
- MISC-3: XP Double-Counting in logXpEvent() behoben
- TYPE-2: awardXP() Parameter-Reihenfolge korrigiert (break, energy, focus)
- DEAD-1: Ungenutzter calculateXP() Dead Code entfernt
