Fix JSON subcolumn file errors due to unescaped special symbols

Official CH changelog text
Fix possible error No such file or directory due to unescaped special symbols in files for JSON subcolumns. #71182 (Pavel Kruglov).
Fixes the No such file or directory error caused by unescaped special symbols in files when querying JSON subcolumns.

Why it matters

This fix addresses an issue where special characters in file paths were not correctly escaped, leading to errors when accessing JSON subcolumns. It ensures robust handling of file paths with special symbols, preventing query failures and improving reliability.

How to use it

Users do not need to change their queries or configurations. The fix is applied internally in how file paths for JSON subcolumns are processed, so upgrading to this version will automatically resolve the error.
