feat: add scan lifecycle tests for clean + quarantined status using EICAR

Ports the pattern from the Python CMA SDK tests (test_06_asset.py,
test_31_am_assets.py) to JavaScript.

New helpers:
  - EICAR_BASE64: standard 68-byte EICAR signature stored base64-encoded
    so source file is never flagged by Talisman / repo antivirus scanners
  - createEicarFile(): decodes to a temp file at runtime, deleted in after()
  - waitForScan(stack, uid, expected, timeout=60s): polls
    fetch({include_asset_scan_status:true}) every 3s until status matches
    or times out; treats not_scanned as terminal (feature disabled on stack)

New describe: 'Asset Scan Status – Scan Lifecycle (clean + quarantined)'
  - clean image → polls until 'clean'
  - EICAR file → polls until 'quarantined'
  - quarantined download → verifies SDK surfaces 403/422 with scan error code
    (§ 3.3 re-tested with a REAL quarantined asset, not a fake URL)

AM org additions (AM-8, AM-9):
  - [AM] clean image transitions pending → clean
  - [AM] EICAR file reaches quarantined status

Also adds: import fs from 'fs' and import os from 'os'

Verified locally: 37 passing, 0 pending, 0 failing
