fix: use correct pyright ignore syntax for optional logfire import

Changed from 'pyright: ignore' to 'pyright: ignore[reportMissingImports]'
to properly suppress the import error for the optional logfire dependency.

Logfire is only imported when cloud_mode is enabled and is wrapped in
a try/except ImportError block, making it truly optional.
