fix ordering of attributes being used before being introduced

The compiler was complaining about the following:

warning: derive helper attribute is used before it is introduced
--> src/services/pool/types.rs:357:3
|
357 | #[serde(tag = "op")]
| ^^^^^
358 | #[derive(Serialize, Deserialize, Debug)]
| --------- the attribute is introduced here
|
= warning: this was previously accepted by the compiler but is being phased out; it will become a hard error in a future release!
= note: for more information, see issue #79202 rust-lang/rust#79202

This PR reorders the two code lines so that the attribute is used after being introduced

I think the build failure is not due to this PR.

@AxelNennker, you are correct, it is not. A fix for the build issues has been implemented (#2470), which should have also addressed the changes you made here. Please confirm and close the PR is this is the case.
