feat: 添加 LP 流动性池边界测试

新增 LP 边界测试功能:
- 添加流动性边界测试:
  - 添加金额为0 (InvalidAmount)
  - 添加超过代币余额 (InsufficientBalance)

- 移除流动性边界测试:
  - 移除金额为0 (InvalidAmount)
  - 移除超过ytLP余额 (InsufficientBalance)
  - 移除时minOut过高 (InsufficientOutput)

- 代币互换边界测试:
  - 互换金额为0 (InvalidAmount)
  - 相同代币互换 (SameToken)
  - 互换超过余额 (InsufficientBalance)

UI功能:
- 可折叠的边界测试区域
- 显示冷却时间和ytLP余额状态
- 中英文翻译支持
