List a subscription's pass moves

curl https://api.subscriby.net/v1/subscriptions/$SUBSCRIPTION_ID/pass-moves \  -H "Authorization: Bearer $SUBSCRIBY_TOKEN"

Every hop the purchase's passes made, oldest first, from the project's pass move log: a date cancelled and the holder rolled forward (window_cancelled), a season date replaced by another (series_date_substituted), or a payment that settled after the date it was for and was bound to the next one (paid_after_window). Each hop names both dates by id and as a person reads them in the plan's zone, who made it (moved_by_user_id and moved_by_name, null when the platform made it on its own) and when. The ledger rewrites a moved pass in place and keeps only its last move; the log keeps them all, so a pass moved twice answers two rows. A purchase with no dated passes answers an empty list. Moves made before the log existed were carried over once from the ledger with the last move it remembered for each pass.

Reads under project-subscription:view, the subscription's own gate, and resolves the subscription as the token may see it: a stranger's purchase is a 404 RESOURCE_NOT_FOUND. The same hops reach the Pass Roster as departures, and pass.holder_moved carries each one's move_id as it happens.
