Subject: Limit scrape window and default event list to ~1 month

Scraper runner now filters events to today + 35 days before upserting,
so the DB only holds the upcoming month of events.

Event list loader defaults date_from/date_to to the same window when
no query params are set, and passes the values down to FilterBar so the
date inputs are pre-filled on first load.
