"""Pier delete test (2026-10-12): own data root (검증/web_delete_test_data, recreated); real piers are not touched.
Checks: wrong / empty confirmation name refused; refused while a batch runs; correct name moves the folder to
data/_휴지통/<name>_<time> with its files; the pier disappears from the list; the trash folder is not listed as
a pier; restoring the folder brings the pier back.
