feat(mosaic): wire up user profile active devices

[austincalvelage]

Description

Wire the Mosaic active devices section to Clerk so users can view sessions and device details, then sign out another device. Show localized activity dates, current-device and impersonation badges, API errors, and retry actions. Keep the details dialog open while sign-out is pending and restore focus after removal.

Session reverification UI is deferred. Requests that require it surface the API error and leave the device in place. Ignore stale work after the active user or session changes. Compose the connected section through the security panel's activeDevicesSlot. Bulk sign-out is deferred, with both gaps documented in feature tests. Full UserProfile assembly is outside this PR.
