With dioxus fullstack, dioxus compiles your app twice: once for the frontend with the web feature, once for the backend with the server feature. You need to make sqlx optional and enable it only in the server feature so it isn't included in the WASM client. See this example: https://github.com/DioxusLabs/dioxus/blob/main/packages/fullstack/examples/axum-auth/Cargo.toml#L18-L26
