fix: use local storage for enterprise auth

[bgrams]

What

Persist the Enterprise webapp login state within the browser to avoid reauthenticating in new sessions. Links that open a new tab or window will otherwise re-initiate the login flow and redirect to the workspace landing page.

This addresses airbytehq/airbyte#63355, but note that the redirect issue still may arise upon "initial" user login, after which navigation is expected to behave correctly. So there still may be an opportunity to improve redirect behavior within the webapp, but this is outside of my expertise.

How

Add a WebStorageStateStore to the react-oidc-context configuration that uses local browser storage for the ID and access tokens.

Thanks for this contribution! I merged a similar PR in our upstream repository, of which airbytehq/airbyte-platform is a mirror. So this change will go out in the next release of the Airbyte platform.
