Fix lint warnings in recently modified files

- RouteCanvas: @ts-ignore → @ts-expect-error (ban-ts-comment rule), prefix unused `id` prop with underscore
- useRenpyAnalysis: remove unused type imports (Link, DialogueLine, VariableUsage)
- renpyValidator: remove dead VOICE_KEYWORDS constant
- renpyValidator.test: remove unused msgs() helper (superseded by errors()/warnings())
