Conversation
Replace the `&'db mut dyn DatabaseExt` lifetime parameter with a generic `DB: Database<Error = DatabaseError> + Debug` bound across FoundryEvm, FoundryHandler, EthRevmEvm, and related functions. Call sites in backend/mod.rs and backend/cow.rs updated to explicitly coerce to `&mut dyn DatabaseExt` where needed.

Motivation
Replace the
&'db mut dyn DatabaseExtlifetime parameter with a genericDB: Database<Error = DatabaseError> + Debugbound acrossFoundryEvm,FoundryHandler,EthRevmEvm, and related functions. Making them perfectly aligned with alloy-evm patterns.Call sites in backend/mod.rs and backend/cow.rs updated to explicitly coerce to
&mut dyn DatabaseExtwhere needed.
