Move all module-level imports to the top of affected files and remove
late imports after sys.path manipulation or runtime code.
Also normalize test imports to use package paths instead of ad-hoc
sys.path hacks, aligning tests with the new layered architecture.
No functional changes intended.

- Fix E402 by removing sys.path hacks and ensuring imports are at module top level
- Replace ad-hoc imports with proper package imports (filter_plugins, lookup_plugins, module_utils, cli)
- Make lookup plugins importable via package paths (e.g. lookup_plugins.application_gid)
- Clean up test imports to rely on installed package layout instead of sys.path manipulation
- Partially fix F821 caused by missing/invalid imports
This establishes a consistent, ruff-compliant import architecture across CLI, filters, plugins, and tests.
