Archive: management-dashboard-web-app legacy/backup files

Moved from management-dashboard-web-app/ so the app directory only contains active code and config.

env-backups/ – Old .env.backup and timestamped backup (Supabase URL/key). Keep out of version control if they contain secrets.
experiment-data/ – CSV run sheets: phase_2_JC_experimental_run_sheet.csv, post_workshop_meyer_experiments.csv. Source/reference data for experiments.
test-api-fix.js – One-off test script for camera config API; not part of the app build.
