fix: move dispose_engine import inside lifespan function

The top-level import of dispose_engine from cartsnitch_api.database
caused ImportError at module scope because dispose_engine was not
available when main.py was loaded. The function is only used inside
the lifespan context manager, so move the import there.

Fixes: ImportError cannot import name 'dispose_engine' from 'cartsnitch_api.database'
