refresh_view()/refresh_rows()/update_loading() don't re-sync ViewAction button state

[gkennos]

Pre-flight

• I searched existing issues and this is not a duplicate.

Summary

Workbench.show_surface() calls show_actions(view.actions) to sync each ViewAction button's label/variant/disabled state, but the two in-place refresh paths used by refresh_view() never called show_actions()

when a page is rendered via show_view(), subsequent refresh_view() calls leave action buttons stuck at whatever state they had on first render, even if the view's actions change on every refresh

Reproduction

run a long job with a button

Actual behaviour

add self.show_actions(view.actions) to both refresh_rows() and update_loading() in src/groundskeeping/widgets/workbench.py

Expected behaviour

show_actions(view.actions) is called every time a view is refreshed so that downstream consumers don't need to keep calling refresh as per the old flickering refresh path
