feat(clients): add bulk enable/disable and move selection actions into More menu

Add bulkEnable/bulkDisable named endpoints backed by a shared internal impl, and consolidate the per-selection actions (attach, detach, add to group, ungroup, enable, disable, adjust, sub links) into the clients table's More dropdown so the toolbar only shows the selection count and delete. Translate the new enable/disable confirm dialogs and toasts across all 13 locales.
