At least one less SSO click per day. Customer ask.

When a stale ID token is found, transparently triggers the Vault OIDC flow rather than requiring a user click through (shown below).

Following the standard procedure (e.g. https://github.com/DataDog/dd-source/pull/104445).

## Test Plan

### Self

```
// from the console, set a stale token
localStorage.setItem("AuthUser", '{"idToken":"eyJhbGciOiJSUzI1NiIsImtpZCI6IjY3YWEyNmIxLTMzODQtZGEzMi04M2E4LWIyOGMwMDU4MDI3YyJ9.eyJhdWQiOiAiYXRsYXMtc3RhZ2luZyIsICJkYXRhY2VudGVyIjogInVzMS5kZGJ1aWxkLmlvIiwgImVtYWlsIjogImJyZW5kYW4uZ2Vycml0eUBkYXRhZG9naHEuY29tIiwgImV4cCI6IDEwMCwgImdyb3VwcyI6IFtdfQo.aGE8Z2oH8NKq9X_3ivuaXsc2J_WSh71tT4_HQZlEHDPBP87uX6lYVITjLTCQSYpA5sABqmFCLHpL6VAMC9B53cFk4j5D9Gxg7pFfnVbPfafSg4iuaoB4AzAd_Gyyzf2cEzxqWcl1oaxTti69EcsjE-BronbnY74k8sGMsegKjqormsHg4QsuzOOY8q2ZPtU1pYuslCY0QeBbtfBb9vInsSocopREptl20q37e3QRGRV0031mn2ZR4qW0zM7YD1IstbUDWJioDAl2cpJL-VoUkqrRCCfUbNFBaKcQHurJMRCopRcK999499XSNR423VcbAFc9ezFim5al6uGBOHTrDw=","name":"brendan.gerrity","email":"[email protected]"}');
```

Refresh and watch the console to see the redirect. Shouldn't see the login page.

Tested both with and without proxy in gizmo.

## Risks

There may be some security conventions or best practices that users should click or take an active step.
