feat(theme): 重构颜色系统为双主题设计并添加渐变组件

Browse Source 
- 引入 "The Kinetic Vault"（深色）和 "The Ethereal Terminal"（浅色）双主题系统
- 重构颜色方案，使用层次化 surface 容器替代边框，遵循无边框设计规则
- 添加渐变预设（CTA、买入/卖出、资产卡片）和渐变按钮组件
- 更新圆角系统，明确按钮、卡片、输入框和标签的圆角规范
- 统一文本样式系统，使用 Space Grotesk（标题）和 Manrope（正文）字体
- 更新现有组件（AssetCard、CoinCard、TradeButton）以遵循新设计规范
- 添加向后兼容的已废弃常量，确保现有代码正常运行
