Extend header flip to bundle deployment state filer

bundle/deploy/filer.go has its own stateFiler that fetches the bundle
deployment state from /api/2.0/workspace-files/ using client.Do() directly
(bypassing generated SDK service methods). Apply the same X-Databricks-Org-Id
→ X-Databricks-Workspace-Id swap here so bundle deploy/summary against
unified hosts uses the new routing header consistently with the rest of the
CLI.

Method renamed orgIDHeaders → workspaceIDHeaders for consistency with the
other filer helpers updated in this PR.
