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

[Arthur Bied-Charreton <a.bied-charreton@proxmox.com>]

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

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