chore(parcel-sync): disable auto-refresh scheduler during GIS DB overhaul

Prevents nightly delta sync (Mon-Fri 01-05) and weekend deep sync
(Fri-Sun 23-04) from writing to GisFeature/GisUat while the schema
is being reworked. Re-enable by uncommenting the import in
src/instrumentation.ts once the new DB layout is stable.
