Subject: [PATCH] =?UTF-8?q?UI:=20=E2=80=9EEinloggen=20als"=20je=20Reseller?=

ResellersView: pro Reseller ein „Einloggen als" → impersoniert den Reseller-Admin
(login + ROLE_RESELLER_ADMIN der zugehörigen Firma) → Wechsel in Reseller-Kontext.
Eigene Plattform-Org (nur Plattform-Admins) bekommt korrekt keinen Button.
