fix(auth): update PocketBase v0.23+ auth endpoint and rename users collection

- Replace deprecated /api/admins/auth-with-password with
  /api/collections/_superusers/auth-with-password in both the
  SvelteKit UI (pocketbase.ts) and Go scraper (pocketbase.go)
- Rename custom users collection to app_users to avoid name clash
  with PocketBase's built-in users auth collection
- Fix docker-compose volume mount path pb/pb_data -> pb_data so
  persisted data matches the entrypoint --dir flag
- Add PB_ADMIN_EMAIL/PB_ADMIN_PASSWORD env vars to pocketbase service
  so the superuser is auto-created on first boot
