Batunet/cookie-consent-bundle — reverse-engineered prompt

Build me a Symfony bundle that adds a cookie consent bar to a website so it helps with GDPR and AVG cookie compliance.

I want it to be easy to drop into a Symfony app and render in Twig, ideally in a way that avoids caching issues. The banner should support a light and dark look, show at the top or bottom, and let me configure cookie categories like analytics, tracking, marketing, and social media. It should also support a simpler mode where people can only accept all or deny all.

When someone saves their choices, store them in cookies for about a year, including a consent timestamp, a unique key, and per category yes or no values. I also want an option to log consent choices to the database with anonymized IPs, since site owners may need a record of what users agreed to.

Please include Twig helpers so templates can check whether a category is allowed and whether consent was already saved. Make the texts and styling easy to override, and look up current Symfony docs online if you need to.
