With ?embed=grafana on the URL the board hides its in-page range picker and drives the finished-figures 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 range) is untouched. Includes rebuilt dist.
