- Fix compatibility issues: ActiveSupport EncryptedConfiguration with Psych 4, ActiveRecord PG.connect keyword‑args deprecation warnings, and MySQL bulk‑fixture insertion errors.
- Resolve datetime precision and schema dumping mismatches when upgrading to Rails 7.0, and add cache namespace for ActiveModel proxy calls.
- Update assets handling: correct preload link tags for JS modules, revert service‑name param in Active Storage uploads, and add opt‑out for precompiling Active Storage JavaScript.
