Fix: Use namespaced Expression in SQLite.swift

The SQLite.swift library has updated its API to namespace the `Expression` type under `SQLite`. This commit updates the code to use `SQLite.Expression` to ensure compatibility with the latest version of the library.

This change is necessary to build the project with the updated dependency and fixes potential compilation errors.
