Update Framework to Rails 7.2

[awilfox]

• Rails.application.secrets is removed; the secret_key_base accessor in Rails.application has been present since 6.x, so just use that.

• Minor configuration updates for 7.2 defaults.

• Add mutex_m to avoid deprecation warnings for Ruby 3.4.

Ref: AP-270

This includes the SECRET_KEY_BASE setting in build.yml that @danschmidt5189 suggested in Slack, so cc'ing him.

Only other thing of note is that Rails 7.2 enforces HTTPS (HSTS / redirects) in prod, but this shouldn't be an issue since AFAIK all Library endpoints are HTTPS anyway.

[danschmidt5189]

A few minor questions but definitely not blockers.

[danschmidt5189]

Do you know how this behaves behind a proxy that terminates SSL? X-Forwarded-Proto would be https, but the actual connection to the proxy is http.

AVPlayer and Lost-and-Found both have config.force_ssl enabled, so it should be fine here AFAIK.
