Rails 4.2 -> Rails 7.1, Ruby 2.5.9 -> Ruby 3.2.3

Work in progress.

This PR was produced by generating a new Rails 7.1 app with the new
Turbo/Stimulus/Hotwire stack and asset pipeline, adding bootstrap,
and then moving over the .git folder and all other files from the
main branch of the TicketBooth App.

Fixes Issue #58.
