informationpanel: use QTextEdit for filename display to avoid newlines in copied text

QLabel does not support line wrapping at arbitrary positions. The original code achieved word wrap by manually adding newline characters to the text, which resulted in these newlines being included when the filename was selected and copied.

This patch replaces QLabel with QTextEdit for filename display, leveraging QTextEdit's built-in word wrap functionality that handles line breaks purely for display without modifying the underlying text. This ensures copied filenames remain free of unintended newlines.
