wohnungen: drive list info from LLM JSON, tidy header

- Each row's info line now uses the enrichment JSON (rooms, size_sqm,
  rent_total/rent_cold, wbs_required/wbs_type). When enrichment is still
  running we show "Infos werden abgerufen…", on failure "Fehler beim
  Abrufen der Infos"; the scraper fields are no longer rendered in the list
- Move the admin backfill button to the header row as a compact
  "Anreichern (N)" that only appears when there's pending/failed work,
  so it's findable right next to "X gefunden"
- Countdown wobble: new .countdown class forces tabular-nums + 4.2em
  min-width, so neighbours stop shifting every second
- Dot spacing: pull "·" out into its own .sep span so flex gap applies
  on both sides symmetrically
