Add background bulk import for Komoot

Replace the per-tour import UI with a fire-and-forget background job:

- Add `import_batches` DB table tracking status, found/imported/duplicate counts
- Add `runKomootBulkImport` server function that pages all Komoot tours,
  fetches GPX, creates activities, and deduplicates via sync_imports
- Add `komoot-bulk-import` pg-boss job registered at server startup
- Add POST /api/sync/komoot/import to enqueue the job
- Add GET /api/sync/komoot/import-status to return the latest batch
- Replace the Komoot import page with a progress UI that polls every 2s
  while a batch is running and shows found/imported/skipped counts
