Allow personal channel registrations to grant org services

[louis4li]

Summary

• Allow personal channel registration Agent Keys to include organization-owned services when NyxID marks the credential source as allowed.
• Validate scope-plan resource owners per selected service inventory, so org services must still resolve to their actual organization owner.
• Keep organization-owned registrations strict: org registrations still require admin access to services from that organization.

Test plan

• dotnet test test/Aevatar.GAgents.ChannelRuntime.Tests/Aevatar.GAgents.ChannelRuntime.Tests.csproj --nologo --filter ChannelRegistrationAuthorizationPlannerTests
• bash tools/ci/test_stability_guards.sh
• Local registration smoke: personal registration Agent Key accepted org-owned services and materialized updated allowed_service_ids.
