fix(lint): hoist hooks_cli_mod import to top of test_hooks_cli (E402)

The alias was placed below an explanatory comment block introduced by
#1305, which trips ruff E402 (module-level import not at top of file).
Moved next to the existing 'from mempalace.hooks_cli import (...)' line.

CI lint went red on develop after #1305 merged with the failing check;
this re-greens it so subsequent PRs do not inherit the failure.
