Subject: [PATCH] fix(ui): normalize invalid available size to dash in size
 info widget
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When m_availableSize contains a "-" (e.g. from negative value formatting),
normalize it to "-" to avoid displaying invalid available space.

当可用空间值含"-"（如负值格式化结果）时，将其统一为"-"，避免显示无效的可用空间值。

Log: 修复可用空间显示含"-"的异常值
PMS: BUG-204631
Influence: 修复后分区信息中可用空间显示为"-"而非负值，避免界面显示异常。
