fix: remove redundant use super::* import in tests

[Ash739-ux]

Closes #35

Description

Context

In the tests module of contracts/globe-wallet/src/lib.rs, there was a duplicate import block at the beginning of the module.

Problem

The use super::*; statement appeared twice consecutively. While Rust's glob-import semantics permit this without throwing a compiler error (because both statements independently re-export the same names into the tests module's namespace), it is an obvious copy-paste artifact. It also triggers unused_imports or redundant-import lints (such as in cargo clippy), creating unnecessary lint noise.

This minor duplication fits a broader pattern of copy-paste/merge artifacts found elsewhere in this codebase (e.g., duplicate enum variants, duplicate constants).

Fix

Deleted one of the identical use super::*; lines so only one remains at the top of the tests module.

Definition of Done

• Only one use super::*; remains at the top of the tests module.
• Code cleanly passes cargo check --tests without throwing redundant import warnings for this specific block.

This issue shares the same "duplication survived a merge/copy-paste" root cause as the duplicate enum variants and the duplicate MAX_ASSETS constant in this file.
