fix: correct test_curator mock strategy and list content test behavior

- make_curator() now patches app.curator.load_curator_prompt directly instead
  of env var, since PROMPTS_DIR is a module-level constant set at import time
- _append_rule_to_file tests patch app.curator.PROMPTS_DIR via patch.object
- test_list_content: document that passing a list raises TypeError (expected)
