CreateWorkflow and UpdateWorkflow validated TargetServerIDs against the
caller's scope but never checked TargetTags, letting a restricted token
save a workflow with an empty ID list and an out-of-scope tag selector,
then reach those hosts once the scheduler fires it as the system with no
restriction of its own. Add validateWorkflowTargetScope, applying the
same all-or-nothing rule the MCP create_workflow tool already enforces:
resolve the full target set unscoped and scoped, refuse unless they
match. Update the PUT /api/workflows/:id/schedule fleetWide comment to
say why it is safe now (targets are constrained at write time) rather
than repeating the falsified claim that scheduling reaches nothing new.
