Testing Tenant Isolation

Each tenant has its own schema. Data created for one tenant is invisible to others:

# Create user in tenant 'acme'
curl -X POST http://localhost:3000/users \
  -H "Content-Type: application/json" \
  -H "X-Tenant-ID: acme" \
  -d '{"email": "john@acme.com", "name": "John"}'

# List users in 'acme' - returns John
curl http://localhost:3000/users -H "X-Tenant-ID: acme"

# List users in 'globex' - returns empty (different schema)
curl http://localhost:3000/users -H "X-Tenant-ID: globex"
