fix(formatter,oxfmt): Handle nested BinaryExpression for tailwind trailing spaces

[leaysgur]

Fixes #20397

can_collapse_whitespace() walks the ancestor chain looking for BinaryExpression(+) to determine if boundary whitespace must be preserved.

The loop broke on the first non-BinaryExpression ancestor, so a ConditionalExpression (ternary) between the string and the outer + caused an immediate break. So, the BinaryExpression was never seen.

Prettier's canCollapseWhitespaceIn() iterates the entire ancestor path without breaking, reacting only to BinaryExpression(+) and TemplateLiteral nodes via if checks.
