Fix: Missed array expansion in ClamAV scanning message

ISSUE: Line 1759 still used ${SCAN_PATHS[@]} in echo context.

FIX: Changed to ${SCAN_PATHS[*]} for proper array expansion in echo.

This completes the array expansion fixes from earlier commits
(lines 1664, 1759, 1871 now all use [*] for echo context).

NOTE: Command context (line 1765 in clamscan call) still correctly
uses [@] with quotes which is appropriate for command arguments.
