feat(ui): CTAButton 可复用组件 + P5 全站 CTA 签名切换（17 页面 27 处）

feat(ui): 抽离 CTAButton 为 src/components/ui/cta-button.tsx
- 4 variant 覆盖全站 CTA 场景：
  * primary：品牌红填充 pill（hero 主行动 / 底部大 CTA）
  * secondary：描边墨色 pill（浅色 section 次行动）
  * dark：描边浅色 pill（深色区块 bg-dark-bg 内次行动，如 brand/team 底部 CTA）
  * inline：透明 + 小箭头（卡片内次行动）
- 品牌箭头签名化：内置 ArrowRight + hover translate-x 微交互
- 200-300ms transition，对齐项目动效四原则
- data-testid 透传避免破坏既有测试

style(cta): P5 全站 CTA 签名切换（17 页面 27 处）
- home V15 / news×3 / products×4（含 erp）/ cases / services×2 / solutions×2
- brand / methodology / team（hero 2 + L4 2 = 4 处，含 dark variant）
- error / not-found（保留 onClick 功能按钮与卡片式导航 StaticLink）
- 清理：StaticLink / Button / ArrowRight / ChevronRight unused import

test(marketing): services/solutions lucide-react mock 补 ArrowRight
- CTAButton 内部用 ArrowRight，原 mock 漏导导致渲染崩（4 测试失败已修）
- 对齐 home-content-v15.test.tsx 既有 mock 范式

+/**
+ * CTAButton — 全站统一的「行动召唤」组件
+ *
+ * 设计意图（见 .impeccable.md / Phase B P5）：
+ * - Pill 化（rounded-full），与项目 Button 组件 size 体系一致
+ * - 品牌箭头签名化：内置 ArrowRight，hover 时 translate-x 形成微交互
+ * - 四变体覆盖全站 CTA 场景，避免"全是大红 pill"的 UI 噪音：
+ *   - primary：品牌红填充 pill + 大箭头（hero 主行动 / 底部大 CTA）
+ *   - secondary：描边墨色 pill + 大箭头（浅色 section 次行动 / 跳转按钮）
+ *   - dark：描边浅色 pill + 大箭头（深色区块（bg-dark-bg）内的次行动，如 brand/team 底部 CTA）
+ *   - inline：透明 + 小箭头 + 文字色（卡片内"了解更多"轻量次行动）
+ *
+ * dark 变体于 2026-08-31 P5 批次 4 新增：brand/team 底部深色 CTA 区块的次行动此前用
+ * text-dark-text-primary + border-dark-border 手写描边，现统一进组件，避免深色背景上误用
+ * secondary（text-ink）导致不可见。
+ * - 200-300ms transition（动效四原则区间内）
+ * - 主行动（primary）触达品牌红 #C41E3A 单电压，遵循"每页 ≥ 3 处品牌红触达点，面积 ≤ 10%"约束
+ *
+ * 抽离自 src/app/(marketing)/home-content-v15.tsx (2026-08-31)，原 primary/secondary 行为完全保留；
+ * 新增 inline 变体支持次行动场景；data-testid 透传避免破坏既有测试快照。
