devSharaku e871557bf2 Update Xbox backend to 0.2.12 and accept compact JWE tickets (#1729) 
Some Microsoft accounts get a delegation-compact (d=) ticket, which the
pinned Xbox backend (Nexus 0.2.8) rejected: the library stayed empty
(store-ticket-format) and downloads failed. This moves the backend to
Nexus 0.2.12, which has the upstream store-ticket fix, rebases the
DroidDeck credentials, launch-view and cloud-token patches, and strips
the d= prefix from compact JWE tickets so downloads work again.

Tested by seven users in the Discord Xbox Store Issues thread on the
pr-1729 build at d55e05a0.

* Update Xbox backend to 0.2.12
* Fix cloud offering fallback and add regression tests
* Fix Xbox authentication with compact JWE tickets
