With ?embed=grafana on the URL the terminal hides its in-page window picker and drives the listed-carts window from Grafana's exact from/to (epoch ms) instead of a preset. Backend /overview now accepts from/to (aliased) via FROM_UNIXTIME, which resolves in the same DB session clock as NOW() so timezone handling is unchanged. Standalone behaviour (own picker + preset window) is untouched. Includes rebuilt dist.
