Description
Upgrade Rails from the current ~> 7.2 (locked at 7.2.3.1) to the 8.x series. Rails 8.0 was released in late 2024 and brings Solid Queue / Solid Cache / Solid Cable as defaults, Propshaft, Kamal 2, Authentication generator, and a number of framework deprecations.
https://rubygems.org/gems/rails/versions
The previous Rails upgrade (7.0 → 7.1) was tracked in #5462; we should follow the same incremental approach: 7.2 → 7.3 (if applicable) → 8.0, resolving deprecation warnings before each step.
See: https://guides.rubyonrails.org/upgrading_ruby_on_rails.html#upgrading-from-rails-7-2-to-rails-8-0
