Update remaining Gems to current versions

Notable changes:

* Rack 3.x sends all HTTP headers uncapital.  I don't like it either,
  but that's the way it is.  Any case-sensitive header matching will
  need to be updated accordingly.

* Puma 4.x doesn't slot into Rack 3.x, so we are now on Puma 7.  There
  are no configuration differences between them, and it seems to even
  run a little faster.

* Rubocop added more checks; the only one that caught anything was
  `RSpecRails/HttpStatusNameConsistency`, where we were using the
  deprecated `:unprocessable_entity` symbol instead of
  `:unprocessable_content`.

* Selenium 4 removes the ability to specify Chrome logging parameters
  the way we were doing it.  There is a (slightly more complex) way to
  do it, but `ALL` seems to be the default now anyway, so just remove
  this for now.

* Brakeman 8 brings full Rails 8 compatibility.

* Lots of other security, bug, and QOI improvements.

Closes: AP-270
