## Summary
- add a shared provider target-scope descriptor, normalizer, identity-context metadata, and surface-summary layer
- update provider connection list, detail, create, edit, and onboarding surfaces to use neutral target-scope vocabulary while keeping Microsoft identity contextual
- align provider connection audit and resolver output with the neutral target-scope contract and add focused guard/unit/feature coverage for regressions
## Validation
- browser smoke: opened the tenant-scoped provider connection list, drilled into detail, and verified the edit/create surfaces in local admin context
## Notes
- this PR comes from the session branch created for the active feature work
- no additional runtime or persistence layer was introduced in this slice
