fix(lint): enforce consistent-type-imports and fix import ordering across codebase

Auto-fix 862 lint errors: convert value imports used only as types to
`import type`, fix import group ordering in seed.ts and du-an-api.ts,
remove unused imports in auth controller, and clean up stale eslint-disable
comments referencing non-existent rules.
