fix(ucm): use top-level SectionDevice in HiFi.conf for ALSA parser
Nested SectionVerb caused alsaucm "no use case device defined", so PipeWire never exposed the HiFi profile. Document alsaucm check and reinstall path. Made-with: Cursor

**若 `pactl set-card-profile … HiFi` 报「无此实体」**:多半是 **UCM 未成功加载**(WirePlumber 因此注册不出 `HiFi` profile)。先在终端验证 ALSA 能否解析配置:
