Fix bugs and improve robustness of report fetching

- Fix missing 'import sys' in get_report.py that caused a NameError
  on the credential-check error path
- Fix indentation of the per-report print statement in
  report_json_down.py so it prints for every report, not just the
  last one per date
- Replace hardcoded X-ENROLLMENT header value with dynamic extraction
  from selenium-wire intercepted requests
- Replace fragile time.sleep() calls with WebDriverWait so the script
  waits for actual page/login readiness rather than fixed delays
- Remove album_json_down.py, a Windows-only legacy script inherited
  from upstream that was never used in this fork
