J.C. Bartle 9131186bd1 🛠️ fix: centralize OBO identity scoping
Add shared auth identity helpers for app user ids, OpenID subjects,
tenant ids, and normalized OpenID issuers.

Thread a non-placeholder-visible OBO identity context from the real
request user through MCP connection, tool-call, reinit, and refresh
paths. Keep tenantId and openidIssuer out of createSafeUser so MCP
user placeholders do not expose those fields.

Scope OBO token cache and in-flight exchange keys by tenant, issuer,
OpenID subject, scopes, and a SHA-256 hash of the upstream assertion.
This prevents cross-tenant/cross-issuer collisions and avoids reusing
tokens minted from stale rotated assertions.

Use the shared identity helpers for OpenID refresh-flight keys and
refresh-token bridge recovery records so related OBO refresh paths share
the same identity normalization rules.

The helper is intended for auth-boundary and credential-cache code, not
as a blanket replacement for ordinary app user id ownership checks.
