/**
 * Cycle 10 — Unified field worker table.
 *
 * Replaces `water_irrigators` + `time_tracking_workers` (one row per
 * person with two independent PIN hashes) with one row, one PIN hash,
 * one role vocabulary.
 *
 * Role vocabulary (matches the CHECK constraint in
 * `db/migrations/0097_field_workers.sql`):
 *   - `worker`      — default; can submit water entries + clock in/out
 *   - `time_admin`  — can manage time-tracking tasks, settings, and
 *                     other time workers
 *   - `irrigator`   — legacy role from `water_irrigators`; same powers
 *                     as `worker` but kept distinct for UI filtering
 *                     (the water admin UI shows this label)
 *   - `water_admin` — can manage headgates, water workers, and water
 *                     entries
 *
 * The PIN is a scrypt self-describing hash from `@/lib/water-log-pin`
 * (column name `pin_hash`, NOT `pin` — see cycle 10 migration for the
 * rename).
