xsl b61ea6f33b feat(接口5): 生发机制对齐接口2 + 统一ComfyUI重绘提示词
接口5改造(生发机制与接口2一致,按性别分流):
- generate_hairline_pngs: 生发图来源从 _grow_from_texture(局部inpaint)
  改为按性别分流——female走 generate_grow_results_swap(swapHair+Flux整帧重绘),
  male走 generate_grow_results(ComfyUI add_hair)
- 新增参数 redraw_max_side/unet_name/v2_defaults(female路径透传)
- 接口5 handler 加 flux_model/redraw_max_side Form参数
- 保留接口5独有输出: 3档叠图(middle/high/low)/中心点/face_measure
- 已验证: female日志出现"接口2女 管线降分辨率max_side=640"+swap+Flux;
  male走add_hair.json; generate_grow_image=false正确跳过生发

统一ComfyUI重绘提示词:
- "填充遮罩区域的头发,皮肤加一点磨皮,再加一点美颜" → "填充遮罩区域的头发"
- 覆盖: _REDRAW_PROMPT/_DEFAULT_PROMPT常量 + app.py各接口Form默认 +
  工作流JSON节点60(add_hair/0716add-hair-api/hair_repaint) + 全部测试页输入框
