perf(workspace): make the workspace shell Eager components OnPush (#1819)

Plan item C6 step 3 for libs/workspace: the seven Eager components in
workspace/shell/feature, including the workspace shell root the idle audit
found re-rendering on every idle tick. Their templates read signals,
signal inputs, computed values and template-event state only; the one
plain field written outside the template (categoryLockTarget) is not
rendered. They switch to OnPush without other changes.
