* feat: add cable health scoring via sebuf InfrastructureService

Port submarine cable health monitoring from PR #134 to the sebuf
architecture. Adds GetCableHealth RPC to InfrastructureService that
analyzes NGA maritime warnings to detect cable faults and repair
activity, computing health scores with time-decay.

- Proto: GetCableHealthRequest/Response, CableHealthRecord, evidence
- Handler: NGA warning fetch, cable matching (name + proximity), signal
  processing, health computation with redis caching
- Client: circuit breaker, proto enum → frontend string adapter, 1-min cache
- Frontend: health-based cable coloring (fault=red, degraded=orange),
  evidence display in cable popup, SVG + DeckGL support

* fix: address PR review feedback for cable health scoring

- Fix geographic proximity: use cosine-latitude correction instead of
  raw Euclidean distance on lat/lon degrees, return distanceKm directly
- Fix signal kind: use 'cable_advisory' (not 'operator_fault') for
  non-fault NGA warnings so advisories don't trigger fault status
- Parallelize loadCableActivity + loadCableHealth with Promise.all
- Remove console.log from client-side cable-health service
- Add in-memory fallback cache on server so transient Redis+NGA
  failures serve stale data instead of empty response
