Subject: [PATCH] fix: parse JSON error messages and redirect to dashboard
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

1. Parse JSON error responses to extract 'detail' field
   Fixes: {"detail":"..."} shown as raw JSON instead of clean text
2. Redirect 'already_verified' to '/' instead of '/login'
   Fixes: Users land on empty page when already logged in
3. Change button text: "Jetzt anmelden" → "Weiter zum Dashboard"
