Upgrade to Rails 8.0 and adopt new features

- Bump Rails to version 8.0 and execute `rails app:update` for
  configuration alignment
- Recommend Node.js 22 for development and runtime compatibility
- Enhance Dependabot configuration for improved dependency management
- Remove suppression of SQLite production warning, addressing
  rails/rails#50463
- Use an example domain for email addresses in test suites
- Reorder certain path assertions after text assertions in specs to
  ensure server state is persisted
- Add the frozen string literal magic comment to Ruby files
- Switch to Rails 8’s built-in rate limiter for request throttling

Closes #637
