Adds trashCalendarSyncJob.ts, which pulls Restmüll/Biomüll/Gelbe Tonne/ Papiertonne dates for Nackenheim (CityId 35, Verbandsgemeinde Bodenheim) from the public, keyless API behind lk.kaw-mainz-bingen.de's official waste calendar, and upserts them into trash_schedule. Adds a unique (type, date) constraint to prevent duplicate entries on reruns. Run via `npm run trash-sync:run`, same standalone-script pattern as the other reminder jobs.
