修复 主界面点击音效、谱面预览时 音量不可调节的问题

ping #807

没绷住，谱面预览音量调不了是因为这里写死了 0.7

[YuevUwU]

只是猜测，Mivik的原始意图也可能是Music Volume的0.7倍
#199 也发现了比较小声这件事
0.7可能从prpr的cali音量而来(硬编码，非倍数，那时候已经有这个音量config了)
迁移到了phira的cali.ogg直接套用sasa的默认值1.0了
phira的0.7已经只剩下关于song preview本地create_music函数的两处使用了
既然cali那边phira也改了，就不知道开发者还保不保留这个特性了

[Mivik]

这里还是用使用 volume_music*0.7 比较好

Copy, will take that on my wake time

测试没什么问题，材质包和延迟调节都能吃到这里的设置
回归没跑过，不过应该也差不多
