Rewrite PSN + CityHome scrapers, add price/m² map coloring, ratings system, and status dashboard

- Rewrite PSN scraper to use /api/units-list endpoint (single API call, no HTML parsing)
- Fix CityHome scraper: GPS from multiple URL patterns, address from table cells, no 404 retries
- Color map markers by price/m² instead of disposition (blue→green→orange→red scale)
- Add persistent rating system (favorite/reject) with Flask ratings server and localStorage fallback
- Rejected markers show original color at reduced opacity with 🚫 SVG overlay
- Favorite markers shown as ⭐ star icons with gold pulse animation
- Add "new today" marker logic (scraped_at == today) with larger pulsing green outline
- Add filter panel with floor, price, hide-rejected controls and ☰/✕ toggle buttons
- Add generate_status.py for scraper run statistics and status.html dashboard
- Add scraped_at field to all scrapers for freshness tracking
- Update run_all.sh with log capture and status generation
