feat(web): integrate neighborhood radar chart into listing detail page

Add NeighborhoodRadarChart to listing detail view, fetching scores
from the analytics API based on the listing's district and city.
Displays a 6-axis radar chart (education, healthcare, transport,
shopping, environment, safety) with overall score and color-coded
badges.
