1) 删除 5 个无用的取数脚本（连同 __init__ 的导出）：
get_game_event / get_game_ng_music_id / get_game_ranking /
get_game_tournament_info / get_game_weekly_data
2) config.py 常量下沉（config 只留「机台/店铺标识」和闸门/日志）：
- BASE_URL / AES_KEY / AES_IV / OBFUSCATE_PARAM -> api/maimai_net.py
- AIMEDB_* / QR_* -> api/chime.py
- TICKET_CREDIT_NUM / TICKET_NAMES / PAID_TICKET_IDS /
TICKET_VALID_HOUR_OFFSET / TICKET_VALID_DAYS -> api/upsert_user_chargelog.py
- PLAY_SPECIAL_NUM -> api/upsert_user_all.py
- PLAY_CHARACTERS -> selftest.py（作为测试数据）
下沉后的常量仍从 api 包统一导出，调用点无需改 import 路径。
3) PlayData 字段改造：
- characters 默认空列表（真值由 derive_play_characters 从快照推）
- local_play_count 恒为 2
- after_grade_rank 恒为 1
4) rating / grade 改为运行时从服务器快照取：
- 新增 derive_play_rating()：
before/afterRating <- userData.playerRating
before/afterDeluxRating <- userData.musicRating
（真机实证 userRatingList[0].rating 是 0，不是这个值）
- 新增 derive_play_grade() + find_music_detail()：
在 userMusicDetailList 里搜同 (musicId, level) 取 scoreRank
DERIVE_GRADE_FROM_MUSIC_DETAIL=False 可切回严格复刻真机（一律 0）
⚠ 源码实证这三个字段其实是段位 Dan（VOExtensions.cs:1419-1421）

chime.py —— 扫码登录（二维码 -> userId + token）
|

================================================================================
|

功能：把微信二维码串（或二维码 URL）交给 aimedb 服务器，换取 userId 与 token。
