Walkthrough

Removed redundant loop-variable capture re-declarations (tc := tc) from multiple test loops in x/svc/keeper/msg_server_test.go, replacing them with direct tc usage. This change eliminates an outdated Go idiom without altering test logic or behavior.

Poem

🐰 Old loops had shadows, now they're bright and clear,
The duplicate assignments disappear!
One tc to test them, efficient and clean,
The tidiest tests we've ever seen! ✨
