Org-Level Cost Dashboard - 3-Query Parallel + 1 Sequential Pattern

COS1-01: HITL runs `runbooks finops dashboard --timeframe monthly --profile $AWS_BILLING_PROFILE`
and gets accurate multi-account cost report in <30s.

Architecture:
- Auto-detects org-level billing profile (payer account) via LINKED_ACCOUNT probe
- 3 parallel CE queries: account costs, service costs, prev account, prev service
- ThreadPoolExecutor(max_workers=3) with Semaphore(5) for CE rate limit
- Returns None if profile is not an org billing account (fallback to single-account)
