Bug:
fix: optimize search edit widget signal connection

- Change textChanged signal to textEdited to avoid unnecessary signal emissions
- Remove redundant DTK macro check for DSizeMode header
- Fix signal-slot connection to prevent potential text processing issues

Log: This commit fixes the search widget's behavior by using textEdited instead
of textChanged signal, which only triggers when user actually types or
modifies the text, avoiding unnecessary signal emissions from programmatic
text changes.
