[PATCH] fix #7337: Keep track of deep link on OpenID login

[Arthur Bied-Charreton]

Previously, when opening a deep link without being logged into PBS, the
hash was getting lost, redirecting the user to #pbsDashboard instead of
/#<deeplink>.

Store `window.location.hash` in sessionStorage (per-tab storage) before
redirecting to the login URL, and add it to the history after successful
login to direct the user to the deeplink they opened.

`#pbsDashboard` remains the default redirect if no deeplink is stored.
