feat: 实现预算管理功能界面
1. 预算管理界面 - 创建 BudgetScreen 预算管理主界面 - 支持总览、分类预算、成员预算三个标签页 - 实现预算状态可视化（进度条、超支提醒） - 预算项目的启用/禁用切换 2. 预算编辑功能 - 创建 BudgetEditDialog 预算编辑对话框 - 支持设置预算类型、金额、预警阈值 - 分类预算和成员预算的选择器 - 自动设置月度周期 3. 业务逻辑 - 创建 BudgetViewModel 管理预算状态 - 实现预算的创建、更新、删除功能 - 预算状态的实时计算和更新 4. 导航集成 - 在设置页面添加预算管理入口 - 更新导航系统支持预算管理界面 - 添加预算管理路由 5. 文档更新 - 更新 README 版本历史 - 标记预算管理功能为基本完成 - 更新功能进度状态 注：界面已完成，待实现预算超支提醒和分析报告功能 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
