Matthew Meszaros ba1c10fe19 feat(workers): risk-pool schema + per-mailbox risk band
Threat-level segregation, schema layer. Two new concepts:

  workers.risk_pool ∈ {clean, risky, quarantine}
    buckets shared workers by acceptable risk. Dedicated workers don't
    use it (single tenant = no cross-contamination risk).

  email_accounts.risk_band ∈ {clean, risky, quarantine}
    per-mailbox classification, derived from warmup_health_state by the
    rebalancer (next commit). Never set by user input.

The mapping is one-way and intentionally simple:

  healthy           → clean
  watch, throttled  → risky
  quarantined,      → quarantine
  blocked

Rebalancer code lands in the next commit. This commit just adds:

  - migration 000031 with enums + columns + filtered indexes
  - WorkerRiskPool / EmailRiskBand types + RiskBandFromHealth helper
  - WorkerRepository methods: SetWorkerRiskPool, SetEmailAccountRiskBand,
    GetSharedWorkersByTierAndPool, ListRiskCandidates
  - RiskCandidate result type joining email_accounts + warmup health
    (picks WORST state across pools via CASE ranking) + worker columns
    so the rebalancer can decide migrations in one scan
