feat(mcp): renew the stored SSO identity assertion behind ID-JAG (#35401)
* feat(mcp): renew the stored SSO identity assertion behind ID-JAG

The oauth2_id_jag arm asserts the id_token captured at the user's last
interactive SSO login, and nothing ever renewed it, so an agent holding a
brokered LiteLLM key could act for that user only until that token's exp.
The assertion already carried the IdP refresh token beside it; this
redeems it.

RefreshingSSOAssertionStore wraps the database reader and satisfies the
same protocol, so the egress arm is unchanged. Renewal is lazy and
single-flighted per user through the same RefreshCoordinator the
authorization_code arm uses, since an IdP that rotates refresh tokens
treats two concurrent redemptions as replay. A refusal leaves the expired
assertion in place so the reader still challenges the user; an
unreachable IdP surfaces as a store outage instead.

* fix(mcp): let a cross-replica loser settle the SSO assertion renewal itself
