📔 Objective

Forces the icon URI check for crypto v2 users. This adds some plumbing through the key store, which now also includes other non-key cryptographic state. The account security version is expected to be used in many other places that have access to the key store and we do not want to pass through an additional struct to all places.

Please see the tickets for context about what specifically this change achieves.

Further, this fixes the icon uri check to be constant time.
