fix(audit): Batch 2 生产代码 unwrap 替换 (20 处)

P0 修复:
- viking_commands.rs: URI 路径构建 unwrap → ok_or_else 错误传播
- clip.rs: 临时文件路径 unwrap → ok_or_else (防 Windows 中文路径 panic)

P1 修复:
- personality_detector.rs: Mutex lock unwrap → unwrap_or_else 防中毒传播
- pptx.rs: HashMap.get unwrap → expect (来自 keys() 迭代)

P2 修复:
- 4 处 SystemTime.unwrap → expect("system clock is valid")
- 4 处 dev_server URL.parse.unwrap → expect("hardcoded URL is valid")
- 9 处 nl_schedule Regex.unwrap → expect("static regex is valid")
- 5 处 data_masking Regex.unwrap → expect("static regex is valid")
- 2 处 pipeline/state Regex.unwrap → expect("static regex is valid")
