Fix remaining translation key: common.all_nodes

Replaced non-existent common.all_nodes key with common.all_entity pattern.

- advertisements.js: Use common.all_entity with entities.nodes
- map.js: Use common.all_entity with entities.nodes

All translation keys now properly resolve across the entire dashboard.
