sumocoders/FrameworkCoreBundle ? reverse-engineered prompt

Build me a shared Symfony bundle for our apps that gives us the usual site stuff out of the box.

I want it to handle page titles, breadcrumbs, navigation menus, file and image uploads, encrypted fields, audit logging, pagination, and a basic frontend design system so our projects all feel consistent. Make it something I can drop into a Symfony 8 app and use with Doctrine, with sensible defaults and clear docs on how to wire it up in a new project.

Please include the bundle code, templates, assets, config, tests, and any example setup needed so it’s easy to understand and extend. If you need to check the latest Symfony or Doctrine docs for best practices, go ahead and look them up. Keep the implementation clean and practical, since this is meant to be a reusable foundation for multiple projects.
