Post-RFC#637, canvas users send X-Workspace-ID (their identity workspace
UUID). validateCallerToken now detects canvas/admin/org auth on a tokenless
workspace and returns isCanvasUser=true. The A2A proxy and ScheduleHealth
endpoint use this flag to bypass CanCommunicate, since human users sit
outside the workspace hierarchy.

Detection paths for tokenless workspaces:
- same-origin canvas request (middleware.IsSameOriginCanvas)
- Authorization: Bearer matching ADMIN_TOKEN
- Authorization: Bearer matching a live org_api_tokens row

Also fixes mcp_tools.go which was calling MCPHandler.proxyA2ARequest
(5 args) with an extra argument.

Fixes #1674
