AI skill: SKILL.md, AI contract, scrubbed references, eval fixture (d)

- rpa-dashboard-ai/SKILL.md: trigger description and the shared question flow;
  points at the no-AI frontend.md, themes and palette instead of copying them.
- templates/contract.md: runs, review rows, endpoints and the server approve gate.
- Superbill extracts: patient names and the client name removed, every file
  carries an EXAMPLE ONLY banner. tests/test_reference_scan.py checks both skills
  for patient data, internal IPs, credentials and keys.
- tests/fixtures/d-ai-extraction and its eval entry, which runs page_check_ai
  on the built folder.
