Extract duplicated retry logic from OverpassService and RoutingService
into a shared resilience framework in service_policy.dart:
- ResiliencePolicy: configurable retries, backoff, and HTTP timeout
- executeWithFallback: retry loop with primary→fallback endpoint chain
- ErrorDisposition enum: abort / fallback / retry classification
- ServicePolicy + ServicePolicyResolver: per-service compliance rules
(rate limits, caching, concurrency) for OSMF and third-party services
- ServiceRateLimiter: async semaphore-based concurrency and rate control
OverpassService now hits overpass.deflock.org first, falls back to
overpass-api.de. RoutingService hits api.dontgetflocked.com first,
falls back to alprwatch.org. Both use per-service error classifiers
to determine retry vs fallback vs abort behavior.

Preview/PR builds don't have access to GitHub Secrets, so the OAuth
client IDs are empty. Previously this caused a runtime crash from
keys.dart throwing on empty values. Now we detect missing secrets
and force simulate mode, which already fully supports fake auth
and uploads.
Also fixes a latent bug where forceLogin() would crash with
LateInitializationError in simulate mode since _helper is never
initialized when OAuth setup is skipped.

- Gate full error response body logging behind kDebugMode; truncate to
500 chars in release builds to avoid log noise and data exposure
- Add RoutingService.close() and call from NavigationState.dispose()
