fix: accept fractional usage.duration in Ali video task results

[feitianbubu]

⚠️ 提交说明 / PR Notice

阿里视频任务(如 happyhorse-1.0-video-edit)成功后，查询响应里的 usage.duration 可能是浮点数(实测返回过 13.93、20.02)。dto.IntValue 之前只按 int → string 两步解析，无法解析小数。

改为先按 float64 解析再截断取整，字符串分支同样换成 ParseFloat，int / 浮点 / 数字字符串三种形式都能解。这条路径的 usage 不参与计费(ParseTaskResult 只读状态和 URL)，截断没有计费影响。附了表驱动测试。

Walkthrough

IntValue.UnmarshalJSON now accepts floating-point JSON values and numeric strings by parsing them as float64 before converting to int. Tests cover integer, float, negative, string, non-numeric, and boolean inputs.

Changes

Numeric IntValue parsing

Layer / File(s)	Summary
Numeric parsing and validation dto/values.go, dto/values_test.go	IntValue parses numeric values and strings with floating-point support, while table-driven tests verify accepted numeric forms and rejected non-numeric inputs.

Estimated code review effort: 2 (Simple) | ~10 minutes

Poem

A rabbit saw numbers hop and sway,
From "5.0" to 13.93.
IntValue caught them with a grin,
Floats and strings now tumble in.
Bad inputs stay outside the den! 🐇
