Show "(Aktiv)" + remaining time on the white lion mount seal

The slot-highlight for activatable items (uiinventory.py) read
metinSocket[0], which the server now uses for the seal's remaining
usage-time countdown instead of the active flag - moved the check to
socket[2] to match.

Tooltip now shows "(Aktiv)" plus the standard remaining-time line
(reusing the existing AppendTimerBasedOnWearLastTime renderer) for any
IS_MOUNT_SEAL item, replacing the generic ITEM_TYPE_UNIQUE tooltip
logic that would otherwise have misread the active-flag socket as a
unique-item decay timestamp.
