Check Chart/Mdim Preview on Staging

Visually verify that a chart or multidimensional indicator page renders correctly on the staging server.

Prerequisites

• The agent-browser skill must be available (for browser automation)
• A staging server must be running for the current git branch (check via curl -s -o /dev/null -w "%{http_code}" http://<container>/)
• The chart/mdim must have been pushed to staging already (either via etlr --watch in VSCode or manually)
