Fix: formatDate-Kollision, implizites event, onclick-Escaping

- formatDate() in source-health.js zu formatDateTime() umbenannt,
  damit app.js formatDate() nicht überschrieben wird
- searchFix(): data-Attribute statt inline onclick-String (XSS-sicher)
- searchFix(btn): expliziter Parameter statt implizites event.target
