New app: decentralized Pinochle

[NullVoxPopuli]

An old card game with:

• auto-meld finding
• invalid move detection (no renigging allowed)

Goal:

• force myself to clean up all the other PRs that have accumulated since I last worked on emberclear (56 at the time of creating this PR, oof)
• play over zoom or some other video chat (maybe eventually emberclear proper if I ever just figure out how to do WebRTC with the existing stuff)
• automatic multi-game score tracking
• support 3 & 4 player variants
• fancy animations for card playing
• extreme statechart practice
• split up emberclear into addons so that they may be shared with the pinochle app

Depends on:

• convert service injections to declare -- should there be a lint for t… #1162
• fix mobile menu? #1183

Nice to have:

• Integrate @skyrocket/worker so that this project doesn't need to maintain so much code :D #878
• Improved login screen #813
• configure embroider to be on by default #784

Cleanup:

• @use destroyable concept #884
