Remaining dev work before Formative Study 2 session P2

[phrdang]

⚠️ This code is extremely spaghetti code

• Fetch an interesting set of backups (aimed for 25 students in DATA C88C FA25, but ended up with 25 students from CS 61A FA25 since more students met the inclusion criteria)
  • See src/notebooks/ directory to see how students were randomly sampled out of the population that met inclusion criteria
  • See src/backups/config/ directory to see config JSON files for when I attempted to fetch backups for each course and semester pair
  • Add src/backups/email_hash_lookup.py script since the notebooks give us the student email hashes that meet inclusion criteria, but we need to know their actual email to run the backups CLI
  • Update seeds.rb to use 61A FA25 data; also fixed fake student ID generation so the IDs looked more like IDs
• Fix bugs in the frontend and backend of the Print Statements feature, since I wasn't able to test it until now with the more interesting backups set
• Fix bugs in SummaryStatistics controller
  • Fix problem name to score map so it is for 61A FA25 instead of C88C FA25
  • Exclude EC problems
  • Compute total lint errors in final backup correctly
• Fix bug in BackupCalendarChart.jsx where the backup calendar wasn't displaying properly because of time zone differences
• Update Summary tab frontend
  • Fix histogram bins to work with 61A FA25
  • Update time unit from min -> days for total time spent
  • Reduce height of histogram switcher menu thing so it's clearer to the user that there's more graphs below
