Adds a collapsible "How does this work?" panel explaining:
- What the simulator does (live PowerQuery count → GB projection)
- When to use it (after spotting a noisy source in Top Sources)
- How to fill in Source name (copy from dataSource.name column)
- What Event type does (optional narrowing)
- How the GB estimate is calculated
- Warning that it is read-only — no filters are applied automatically
Also updates Source name placeholder to show a concrete example.

- daily-volume: run per-day PowerQueries in parallel with asyncio.gather
instead of sequentially with sleeps — 3 days now completes in ~16s vs 140s+
- Default view changed from 7d to 3d; day buttons updated to [3, 5, 7]
- igLoad: fire daily-volume and top-sources simultaneously with Promise.allSettled
so both panels load in parallel rather than one after the other
- Each panel shows "Querying data lake…" spinner while loading
- Each panel renders independently — one failure doesn't block the other

- First-time setup banner with cp .env.example .env instructions when .env is missing
- Manual setup section with step-by-step terminal commands and where to find each credential
- New .env.example template with comments for all required variables
- Backend: GET/POST /api/settings/config router reads/writes mounted .env file
