fix: Display name truncation

[robertkill]

Center text horizontally in RecognizeDialog paint event

Adjust the x-coordinate calculation in RecognizeDialog::paintEvent to properly center the text within the dialog. The previous calculation did not account for the full width of the text, resulting in misalignment. This change ensures the text is centered correctly.

pms: BUG-307573

Summary by Sourcery

Bug Fixes:

• Correct x-coordinate computation in RecognizeDialog::paintEvent to center text horizontally and prevent truncation.

关键摘要:

• 代码中的 fm.horizontalAdvance(m_text) 返回的是文本的宽度，减去一半后作为 addText 的 x 坐标，确保文本在矩形中居中。
• 代码中的 QColor brushCorlor 可能是拼写错误，应该是 QColor brushColor。

是否建议立即修改:

• 是，建议立即修改拼写错误，以避免潜在的混淆和潜在的错误。

Reviewer's Guide

This PR fixes the horizontal centering logic in RecognizeDialog by updating the x‐coordinate calculation in the paintEvent, ensuring text is centered based on its full width rather than misaligned by half its width.
