- Deleted unused CSV files: 'meyer experiments.csv' and 'phase_2_experimental_run_sheet.csv'. - Updated SQL seed scripts to reflect changes in experiment data structure and ensure consistency with the latest experiment parameters. - Enhanced user role assignments in the seed data to include 'conductor' alongside 'data recorder'. - Adjusted experiment seeding logic to align with the corrected data from the CSV files.
