feat(supply-chain): chokepoint transit intelligence with 3 data sources (#1560)

* feat(supply-chain): replace S&P Global with 3 free maritime data sources

Replace expensive S&P Global Maritime API with IMF PortWatch (vessel transit
counts), CorridorRisk (risk intelligence), and AISStream chokepoint crossing
counter. All external API calls run on Railway relay, Vercel reads Redis only.

- Add 4 new chokepoints (10 total): Cape of Good Hope, Gibraltar, Bosphorus, Dardanelles
- Add TransitSummary proto (field 14) with today counts, WoW%, 180d history, risk context
- Add D3 multi-line chart (tanker vs cargo) with expandable chokepoint cards
- Add crossing detection with enter+dwell+exit semantics, 30min cooldown, 5min min dwell
- Add PortWatch seed loop (6h), CorridorRisk seed loop (1h), transit seed loop (10min)
- Add canonical chokepoint ID map for cross-source name resolution
- 177 tests passing across 6 test files

* fix(supply-chain): address P2 review findings

- Discard partial PortWatch pagination results on mid-page failure (prevents
  truncated history with wrong WoW numbers cached for 6h)
- Rename "Transit today" to "24h" label (rolling 24h window, not calendar day)
- Fix chart label from "30d" to "180d" (matches actual PortWatch query range)
- Add 30s initial seed for chokepoint transits on relay cold start (prevents
  10min gap of zero transit data)

* feat(supply-chain): swap D3 chart for TradingView lightweight-charts

Replace hand-rolled D3 SVG transit chart with lightweight-charts v5 canvas
rendering for Bloomberg-quality time-series visualization.

- Add TransitChart helper class with mount/destroy lifecycle, theme listener,
  and autoSize support
- Use MutationObserver (not rAF) to mount chart after setContent debounce
- Clean up chart on tab switch, collapse, and re-render (no orphaned canvases)
- Respond to theme-changed events via chart.applyOptions()
- D3 stays for other 5 components (ProgressCharts, RenewableEnergy, etc.)

* feat(supply-chain): add geo coords and trade routes for 4 new chokepoints

Cherry-pick from PR #1511: Cape of Good Hope, Gibraltar, Bosphorus, and
Dardanelles map-layer coordinates and trade route definitions.

* fix(supply-chain): health.js v2->v4 key + double cache TTLs for missed seeds

- health.js chokepoints key was still v2, now v4 (matches handler + bootstrap)
- PortWatch TTL: 21600s (6h) -> 43200s (12h), seed interval stays 6h
- CorridorRisk TTL: 3600s (1h) -> 7200s (2h), seed interval stays 1h
- Ensures one missed seed run doesn't expire the key and cause empty data
