feat(storm-intel): Storm Intelligence Hub — Phase 1

Adds a new Storm Intel section to the sidebar and routes for ADMIN and OWNER roles.

- StormIntelPage: full-height layout with Leaflet map + storm polygon overlays,
  severity-coded color system, horizontal filter bar (date range / severity / sort),
  and a scrollable storm event list
- Storm detail drawer slides in from right with hail size, est. homes, days ago,
  conversion window indicator (Hot Zone / Warm / Cold / Too Fresh), intel text,
  and quick-action buttons (Create Lead, Open in Dispatch, Assign Canvassers stub)
- Clicking a storm card or map polygon zooms the map to that polygon and opens the drawer
- useStormEvents hook with USE_MOCK flag, date-range cutoff filter, type/severity filter,
  sort by date or severity, and conversionWindow() helper
- api/storm-events.js: NWS api.weather.gov proxy (free, no auth needed), parses
  GeoJSON polygons and hail size from alert descriptions
- MOCK_STORM_EVENTS: 7 realistic Plano TX storm events with accurate polygon coords
- Sidebar: CloudLightning "Storm Intel" entry added for OWNER and ADMIN nav
