🐛 Bug Fix

Layout content merge: Fixed preg_replace backreference issue in layout content insertion

- preg_replace(pattern, $html, $layoutHtml) treated $ and \ in page content as regex backreferences
- Content containing $2a$04$... (e.g., bcrypt hashes) was corrupted: $2 -> empty, $04 -> empty -> result: a$.j0S6...
- Fix: Escape \ and $ in replacement string using str_replace before passing to preg_replace
