New scraper for reality.bazos.cz with full HTML parsing (no API),
GPS extraction from Google Maps links, panel/sídliště filtering,
floor/area parsing from free text, and pagination fix for Bazoš's
numeric locality codes. Integrated into merge pipeline and map
with purple (#7B1FA2) markers.

- Add 3-attempt retry with exponential backoff to Sreality, Realingo,
Bezrealitky, and PSN scrapers (CityHome and iDNES already had it)
- Add shared validate_listing() in scraper_stats.py; all 6 scrapers now
validate GPS bounds, price, area, and required fields before output
- Wire ratings to server /api/ratings on page load (merge with
localStorage) and save (async POST); ratings now persist across
browsers and devices
- Namespace JS hash IDs as {source}_{id} to prevent rating collisions
between listings from different portals with the same numeric ID
- Replace manual Czech diacritic table with unicodedata.normalize()
in merge_and_map.py for correct deduplication of all edge cases
- Correct README schedule docs: every 4 hours, not twice daily

Scraper changes (all 6 sources):
- Add first_seen: date the hash_id was first scraped, never overwritten
- Add last_changed: date the price last changed (= first_seen when new)
- PSN and CityHome load previous output as a lightweight cache to compute these fields
- merge_and_map.py preserves earliest first_seen when deduplicating cross-source duplicates
Map popup:
- Show "Přidáno: YYYY-MM-DD" and "Změněno: YYYY-MM-DD" in each property popup
- NOVÉ badge and pulsing marker now driven by first_seen == today (more accurate than scraped_at)
Map filters (sidebar):
- New "Přidáno / změněno" dropdown: 1, 2, 3, 4, 5, 7, 14, 30 days or all
- Clickable price/m² legend bands: click to filter to that band, multi-select supported
- "✕ Zobrazit všechny ceny" reset link appears when any band is active
