fix: remove dead dispose_engine import from API main.py

The top-level import of dispose_engine from cartsnitch_api.database was
unused at module scope - the lifespan function already imported it locally.
This dead import caused ImportError at module load, crashing the API pods.

Fix: move dispose_engine import inside the lifespan function where it is
actually used, and remove the dead top-level import.
