chore: remove unused imports and local helpers

Drop module-local helpers that nothing calls (linkAbort, summarize,
stringOption, summarizeEntity and the polygonCenter, propertyObject and
unwrapProperties helpers only it used, CALLOUT_DOT_SIZE_PX) and unused
import specifiers in runtime modules, tests, QA scripts and tools.

None of the removed bindings is exported. Re-exports such as the ALPR
policy constants and every package export are unchanged.
