/**
 * db/proxyLogs.ts — Read queries over the `proxy_logs` table.
 * Extracted from the /api/logs/export route handler.
 *
 * Hard Rule #5: routes must not embed raw SQL — these queries live here so the
 * /api/logs/export route can delegate.
 *
 * NOTE: The SELECT * intentionally returns the historical `public_ip` column,
 * NOT `clientIp`. This differs from GET /api/usage/proxy-logs which exposes
 * the value as `clientIp`. Callers of the export endpoint should read
 * `public_ip`. This inconsistency will be resolved in a future DB migration
 * (#2880).
 *
 * Sliced out of #3500 (proxy_logs cluster, slice 4).
