Dashboard with DB data

• 1) Writing to the database should be done async (thread or active job)
• 2) We need a serializer to store and reconstruct the event_logs
  • Idea: ActiveJob serialization
    • https://edgeguides.rubyonrails.org/active_job_basics.html#supported-types-for-arguments
    • https://github.com/rails/rails/blob/main/activejob/lib/active_job/arguments.rb
• 3) Isolate the serializer that generates the JSON for logging.
• 4) Implement a logging listener that uses this serializer.
• 5) Implement UI to search event logs records.
  • Ideas for the UI.
    • Make with scaffold
    • Use an admin (Avo, ActiveAdmin...)
