Chinese correction: ranslation Consistency & Wording Improvement for "都" and "所有"

Translation Consistency & Wording Improvement

This PR refines the Chinese localization for Clear Statistics to improve clarity, consistency, and natural wording.

1. Remove redundant wording in dialog body

Before

所有的统计数据都将从数据库中删除。

After

统计数据将从数据库中删除。

Reason

• “所有的 (all)” is redundant because “清空统计数据 / Clear statistics” already implies removing everything.
• Shorter text reads more naturally in Chinese UI dialogs.
• Avoids over-emphasis and keeps tone consistent with other confirmation dialogs in the project.

2. Align title wording with action phrasing

Before

清空所有统计数据

After

清空统计数据

Reason

• Removes duplication of the meaning of “all”.
• Matches the simplified wording used in the dialog text.
• Keeps UI titles concise and consistent with common Chinese software localization patterns.

3. Overall benefit

• Improves translation consistency between title and confirmation message.
• Makes the dialog more concise and natural for native Chinese users.
• Keeps terminology aligned with existing UI style (short action titles + concise confirmation text).

No functional changes — localization only.
