HYC-1939 - Change work stats to pulling from local database

[bbpennel]

https://unclibrary.atlassian.net/browse/HYC-1939

• Public work analytics page now pulls download stats from local database
  • Now only pulls 12 months of data, to match the view
• Disabled the public file analytics page, since it was broken
• Updated admin dashboard work analytics page to use local database for download stats
  • matomo.rb now redirects download related events to the local database (for methods that we have known uses of, I did not update all methods)
  • dashboard pulls monthly stats instead of daily
  • refactor of dashboard stat combination to use hashes for look ups, to greatly improve performance
  • Benchmarking added to help pinpoint which parts of the data load are slow. We might want to remove this later, but it'd be helpful to see in prod.
• Admin dashboard now shows all the buttons to get to alternative reports, which were hidden by css issues before
• Bug fix for issue cause fileset_id to be recorded as work id in hyc_download_stats
