MAINT address PR #1960 review: rename class, collapse template enum, add bib entry, docs

- Rename CodeAttackAttack -> CodeAttack (Task 1)
- Collapse language + verbose into a single CodeAttackConverter.Template enum
  modelled on BinaryConverter.BitsPerChar; custom pathlib.Path still accepted
  for caller-supplied YAML templates (Task 2)
- CodeAttack.__init__ now accepts template: CodeAttackConverter.Template | Path
  and forwards it to the converter; language/verbose params removed (Task 3)
- Add @ren2024codeattack entry to doc/references.bib after liu2024flipattack (Task 4)
- Add Code row to the attack table in 1_single_turn.py, add ## Code section
  after ## Flip mirroring the FlipAttack shape, regenerate notebook (Task 5)
- Rebase onto upstream/main (doc/code/executor/attack/ directory was removed
  upstream; old standalone code_attack.ipynb/.py deleted, content moved into
  1_single_turn.py)
- Update all unit tests for the new Template-based API; add custom-Path cases
