fix: remove redundant E2EE banner from members drawer

The banner saying 'E2EE · Shield = verified identity' was cluttering
the top of the member list. Hovering the lock icon in the room header
already communicates encryption status, and tooltips on the shield
badges already explain what verified means. Removed the entire block.
