Return the network services discovered on one asset.

The same set the asset detail response embeds, on its own endpoint so a panel can refresh services without re-fetching the asset. Reads the asset_network_service_details view through its Cerbos-scoped service, so another organization's asset yields an empty list rather than a denial — the asset itself is resolved first, so an asset the caller cannot see still 404s.

Args: asset_id (int): Primary key of the owning asset. db (AsyncSession): Request-scoped database session. context (ActiveContext): Resolved caller identity and scope. query (AssetServiceListQuery): Pagination query params. pager (Paginator): Fills the response's navigation metadata.

Returns: AssetServiceListResponse: The asset's services, each with its detected technologies.
