Add logging to path mismatch fix handler for diagnosis

The fix was failing silently — returning error results without
writing to any log. Added info/warning logs at each failure point
(missing paths, source not found, path escapes transfer, destination
conflict) so Docker path resolution issues can be diagnosed.
