fix(player): persist previous item progress before updating position snapshot

Reorder the position/duration snapshot in ProgressManager.bind() so
stopSession() reads the previous item's last-known position instead
of the next item's seek target. Fixes the offline Room database
being written with 0% progress on item transitions.
