Fix scrapers returning 0 events for 4 venues

Rewrote selectors to match actual HTML structure after inspecting each site:
- LIQUID ROOM: article selector, date extracted from URL (_YYYYMMDD suffix)
- WWW/WWW X: article.column selector, month from li.month nav, day rollover detection
- 新宿 LOFT: section.block_schedule_list links, full date from time div.year/month/day
- CLUB QUATTRO: li[data-event-date] with ISO date attribute, jp-label time parsing

Result: 0件 → LIQUID ROOM 25件 / WWW 48件 / LOFT 13件 / QUATTRO 24件
