Refactor: Improve NFT access control and Superfluid integration

This commit enhances the CookieJar contract by adding robust NFT access control, including validation of NFT contracts and support for checking ownership of any token within a collection (tokenId 0). It also refactors the CookieJarFactory to dynamically fetch Superfluid host addresses based on the current chain ID, improving network compatibility. Additionally, it introduces a new `SuperfluidConfig` library for managing Superfluid network configurations and updates error handling for ETH transfers in `UniversalSwapAdapter`.
