Check-in API: Add reusable media exchange (#6115)

Browse Source 
* Add Reusable Media Exchange to Checkin API

* isort

* Remove debugging leftover

* Apply suggestions from code review

Co-authored-by: robbi5 <maxi@richt.name>

* Add media_exchange_supported to CheckinRPCRedeemInputSerializer

* SecurityProfiles: Add api-v1:reusablemedia-lookup and -detail for SCAN

* Simplify media exchange checks

* Apply suggestions from code review

Co-authored-by: Raphael Michel <mail@raphaelmichel.de>

* Wording: re-usable --> reusable

* Deny checkins if media-exchange is required but device does not support it.

* Remove media_exchange_supported-Flag: Checkin will always be denied if media needs to be exchanged; apps will fall back to explanation text

* CheckinRPC: Also perform media exchange

* Use media_policy from item, not as a checkinrpc parameter

* my own review notes

* Fixes, cleanup, rebase

* block expired media

* Fix query

* add logging

* Refactor link_action into media policy, gift card support

* Block illegal policy-type combination

* Drop add_to_reusable_medium, decide all by policy

* Fix test failure

* fix test on postgres

* Expose reusable_media_usage_enforced to devies

* Explicitly set update view
