feat(gateway): complete edge cache tier coverage + degraded-response policy (koala73/worldmonitor#484)

• Add 11 missing GET routes to RPC_CACHE_TIER map (8 slow, 3 medium)
• Add response-headers side-channel (WeakMap) so handlers can signal
  X-No-Cache without codegen changes; wire into military-flights and
  positive-geo-events handlers on upstream failure
• Add env-controlled per-endpoint tier override (CACHE_TIER_OVERRIDE_*)
  for incident response rollback
• Add VITE_WS_API_URL hostname allowlist (*.worldmonitor.app + localhost)
• Fix fetch.bind(globalThis) in positive-events-geo.ts (deferred lambda)
• Add CI test asserting every generated GET route has an explicit cache
  tier entry (prevents silent default-tier drift)
