feat: include asn in gateway connection metrics

[LucHeart]

Summary by CodeRabbit

• New Features
  • Online device details now include ASN and ASN organization information when available.
  • Gateway connection metrics and connected-hub counts are now grouped by ASN and ASN organization. Unknown values are shown when enrichment data is unavailable.

📝 Walkthrough

Walkthrough

The gateway now enriches connection IPs with ASN data. ASN and organization values flow into online-device records, admin responses, and hub connection metrics.

Changes

ASN data flow

Layer / File(s)	Summary
Enrich connection IPs Common/Services/Geo/IpEnrichmentData.cs, Common/Services/Geo/IpEnrichmentService.cs, LiveControlGateway/Controllers/*, LiveControlGateway/Program.cs, Common/OpenShockServiceHelper.cs, API.IntegrationTests/GeoLocatedWebApplicationFactory.cs	Geo enrichment returns the resolved ASN. The gateway registers geo options and enriches the remote IP before attempting to add a device connection.
Carry ASN into online-device data Common/Redis/DeviceOnline.cs, LiveControlGateway/LifetimeManager/HubLifetime.cs, API/Controller/Admin/GetOnlineDevices.cs	SelfOnlineData and online-device records include ASN and ASN organization. The admin response maps both values.
Add ASN tags to hub metrics LiveControlGateway/Metrics/GatewayMetrics.cs, LiveControlGateway/LifetimeManager/HubLifetimeManager.cs	Hub connection, disconnection, and connected-count metrics include ASN and ASN organization tags. Missing values use Unknown.

Merge Risk: 🔵 Low · up to 80bd8

Hub connections remain available, but connected-count metrics can report an incorrect organization when hubs share an ASN. Group by both tags before merging, or accept this bounded monitoring discrepancy.

Security Architecture Review

Security architecture risk: 🔵 Low · up to 80bd8

Administrator access remains enforced, and unavailable ASN data does not prevent connection admission. No introduced security weakness was established, but monitoring exposure, deployment trust, and mixed-version behavior remain incompletely verified.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

• observed — The administrator endpoint enumerates the online-device collection without a per-owner filter, so the added fields cover the online-device population available to that API. Gateway metrics additionally receive network labels for current connections and connection outcomes.

Trust Boundaries and Controls

• observed — ASN labels come from a database lookup of HttpContext.Connection.RemoteIpAddress, not from request-supplied ASN fields. The peer's network influences the lookup key; any upstream rewriting of the connection address remains a deployment trust question.
• observed — GetOnlineDevices checks the current user's Admin role before reading Redis. The controller also requires an administrator-authenticated session, resolving the supplied uncertainty about the endpoint's authorization controls in head source.

Resilience and Maintainability Implications

• observed — Enrichment precedes lifetime insertion and tolerates absent lookup results. Initialization failure invokes removal; removal verifies controller ownership and lifecycle state, catches disposal failures, and then removes the lifetime. These inspected paths preserve explicit ownership checks while adding telemetry.

Review comments at @LiveControlGateway/LifetimeManager/HubLifetimeManager.cs:
- Around line 78-105: Update the connected-hub aggregation in HubLifetimeManager
to key counts by both ASN and organization, so hubs sharing an ASN but having
different organization tags produce separate measurements. Preserve the
zero-count unknown measurement when there are no hubs, and emit each key’s ASN
and organization tags with its count.
