Add capacity filter for live houses (~100 / 100~300 / 300~)

- Add capacity field to VenueMeta and all 17 scrapers (researched values)
- Add capacity column to venues table with auto-migration for existing DBs
- Add capacity_range filter to queryEvents (small/medium/large)
- Add capacity selector to FilterBar UI
