fix(chip): scope yamllint indentation override + pin remaining objectives

Follow-up hygiene wins on top of 76b9dbe.

packages/chip/.yamllint.yaml
- Replace wholesale 'indentation: disable' with a per-path override.
- Indentation is now enforced for hand-authored YAML in the chip tree.
- The override list covers exactly the 11 generator-owned files whose
  PyYAML safe_dump output uses sequence indentation yamllint flags:
  board/kicad/e1-phone/production/ subtree, three dated audit YAMLs
  under board/kicad/e1-phone/, and docs/evidence/pd/e1-soc-pd-input-contract.yaml.
- Verified by injecting a deliberate mis-indent into a hand-authored
  file: yamllint catches it; reverting restores a clean exit.

packages/chip/scripts/check_e1_phone_board_package.py
- check_end_to_end_readiness: pin the two remaining objectives to their
  authoritative artifacts.
  - component_height_and_enclosure_step → enclosure-fit-execution-package.yaml
  - supplier_footprints_pinouts_and_3d_models → supplier-to-kicad-evidence-map.yaml
- Both anchors are real v1-schema, fail-closed artifacts with forbidden_claims.
- All 9 end-to-end objectives are now pinned (was 7 of 9).

Verified:
  docker run ... make e1-phone-board-package-check  (green)
  docker run ... make clean ci-fast                 (ci-fast complete)
  yamllint .                                        (exit 0)
