Add endpoints and logic for fetching associations by beamtime

Introduced endpoints to fetch pucks, dewars, and samples by beamtime ID. Updated backend logic to ensure consistency between dewars, pucks, and samples assignments. Enhanced frontend to display and handle beamline-specific associations dynamically.
