fix(frontend): enable admin impersonation for server-side rendered requests (#11343)

## Summary
Fix admin impersonation not working for graph execution requests that
are server-side rendered.

## Problem
- Build page uses SSR, so API calls go through _makeServerRequest
instead of _makeClientRequest
- Server-side requests cannot access sessionStorage where impersonation
ID is stored
- Graph execution requests were missing X-Act-As-User-Id header

## Simple Solution
1. **Store impersonation in cookie** (useAdminImpersonation.ts): 
   - Set/clear cookie alongside sessionStorage for server access
2. **Read cookie on server** (_makeServerRequest in client.ts):
   - Check for impersonation cookie using Next.js cookies() API  
   - Create fake Request with X-Act-As-User-Id header
   - Pass to existing makeAuthenticatedRequest flow

## Changes Made
- useAdminImpersonation.ts: 2 lines to set/clear cookie
- client.ts: 1 method to read cookie and create header  
- No changes to existing proxy/header/helpers logic

## Result
- ✅ Graph execution requests now include impersonation header
- ✅ Works for both client-side and server-side rendered requests  
- ✅ Minimal changes, leverages existing header forwarding logic
- ✅ Backward compatible with all existing functionality
