cmd: preserve relative paths for files and adapters in CreateHandler

Previously, filepath.Base() was used which stripped directory information
from file paths, causing issues when files with the same name existed in
different subdirectories. The second file would overwrite the first in
the map, losing the reference to one of the files.

This change preserves the full relative path, fixing the issue described
in the TODO comments that were also removed.

Fixes #10333
