Fix all TODO bugs and implement feature additions

- SCRAPE_TARGETS.md: add 5 missing venues (nine-spices, nishieifuku-jam,
  fever-shindaita, moon-step-nakano, mod-shibasaki)
- Navigation: add 日付別 link to venues.tsx and events.$id.tsx headers
- venues.tsx: add official site external links per venue card
- ScrapeButton: new component with useFetcher-based trigger + 2s polling
  progress UI showing per-venue status and event count
- venues.tsx / events._index.tsx: wire in ScrapeButton
- FilterBar + db.server.ts: add area filter derived from venues, threaded
  through queryEvents
