fix: Agents-Seite in SDK-Layout verschoben — Sidebar + Icons sichtbar

Agents lag in app/(sdk)/sdk/agents/ (separater Route-Group) und erbte
daher nicht das SDK-Layout aus app/sdk/layout.tsx. Verschoben nach
app/sdk/agents/ damit SDKSidebar, ComplianceAdvisorWidget und
SDKPipelineSidebar korrekt angezeigt werden.
