refactor(c-2): C-2a-4c 旧蓝分流·长尾批次 11 文件 22 处

- wishes/ai-chat/child-tasks/tasks-review/OnboardingGuide：交互元素已迁移品牌橙，阴影/光晕/elevation 滞后 -> 机械配套全套 rgba(249,115,22,x)
- PlayfulButton：primary/secondary/clay/focus 阴影跟随按钮色（success/warning/error 已状态配套不动）
- my-posts.write-btn / assessment-plan detail+list.progress-fill：实底 #5B9BD5 -> $brand-primary + 补 lang="scss"
- meal-config 早餐槽 / discover coverGradients[0]：数据类目蓝槽 -> sky 现代化（#38BDF8/#BAE6FD），保早午晚与五槽区分
- 验证：9 页 C-2 before+预期替换==after 逐字节 PASS；discover JS 计数断言；11 文件 node --check PASS；残留 0
