Subject: [PATCH] =?UTF-8?q?DB=20Explorer:=20Standardm=C3=A4=C3=9Fig=20zur?=
 =?UTF-8?q?=20letzten=20Seite=20springen?=
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Backend: page=-1 wird als 'letzte Seite' interpretiert (COUNT + Berechnung)
- Frontend: Tabellen-Klick ruft page=-1 auf statt page=1
- Aufgelöster page-Wert aus API-Response für korrekte Anzeige (34/34 statt -1/34)
