/**
 * Date range helpers for ECM pre-screening endpoints.
 *
 * ECM declares startDate/endDate as `date-time`. A bare `YYYY-MM-DD` is parsed
 * as midnight, so passing the same date for both bounds yields a zero-width
 * range and no rows. The admin UI works around this by sending endDate as the
 * day *after* the user-selected day; we do the same here so the MCP-facing
 * endDate is inclusive.
