Subject: [PATCH] fix(partition): add tolerance to add button enable condition
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add floating-point tolerance when comparing input value with remaining
space to prevent disabling the add button due to precision error.

比较输入值与剩余空间时增加浮点容差，避免因精度误差错误禁用添加按钮。

Log: 修复添加按钮在边界值被错误禁用
PMS: BUG-364667
Influence: 修复后用户输入等于剩余空间时添加按钮可正常启用，提升分区创建交互体验。
