* Remove misleading Workers sub-menu items from admin sidebar
The sidebar sub-items (Job Detection, Job Queue, Job Execution,
Configuration) always navigated to the first job type's tabs
(typically EC Encoding) rather than showing cross-job-type views.
This was confusing as noted in #8590. Since the in-page tabs already
provide this navigation, remove the redundant sidebar sub-items and
keep only the top-level Workers link.
Fixes#8590
* Update layout_templ.go
