selftests: tc-testing: fix list_categories() crash on list type

2026-03-04T05:42:57Z

list_categories() builds a set directly from the 'category' field of each test case. Since 'category' is a list, set(map(...)) attempts to insert lists into a set, which raises: TypeError: unhashable type: 'list' Flatten category lists and collect unique category names using set.update() instead.
