Subject: [PATCH] test(folders): use escaped regex for file name matching in
 drag-and-drop tests

Update folder tests to use an exported escapeRegExp helper when constructing
regex patterns for file name matching. This prevents false positives or errors
when file names contain special regex characters, improving test reliability.
