op-mode: T7403: fix image deletion when a single image ID is provided

Commit a99ca6d11 ("op-mode: T7403: add option for forcefully removing a
container image") did not account for the case where a single image ID is
passed as a string. This led to incorrect behavior during iteration.

Without converting the string to a list, the code iterates over individual
characters of the image ID rather than treating it as a single item. As a
result, the system attempts to delete non-existent container images based
on these characters.
