refactor(plan): 优化计划书字段配置管理

- 重构 useFieldValueTransform 为可复用组件，支持动态字段定义
- 优化 PlanFormContainer 字段映射逻辑，简化代码
- 添加计划书模板字段配置：withdrawal_start_age_simplified 等字段
- 改进字段值转换 composable 的灵活性和可配置性
- 更新 CHANGELOG.md 记录本次优化内容

影响文件:
- src/components/plan/PlanFormContainer.vue
- src/components/plan/PlanTemplates/*.vue
- src/composables/useFieldValueTransform.js
- src/composables/useFieldDependencies.js
- src/config/plan-templates.js

 ### 权限与测试

+#### [2026-02-14] - 提取字段分组修正
+
+### 变更
+- 指定提取金额字段改为独立 key，避免与固定提取字段混用
+- 最高固定提取金额仅保留“按年岁：由几岁开始/提取期”
+- 提交映射按提取模式覆盖正确的年龄与年期字段
+
+### 测试
+- pnpm test（通过）
