Update tell position logic and add new endpoint

Refactored tell position logic to use `segment` and `puck_in_segment` fields, replacing the previous single `tell_position` field. Introduced a new `/set-tell-positions` endpoint for setting tell positions based on these changes and removed the deprecated endpoint handling the old logic. Enhanced validation and streamlined handling of related logistics and puck events.
