/**
 * @brief Delete all rows from statistics tables and vacuum the database.
 *
 * This function is called when `TRUNCATE` commands are executed on statistics
 * tables via the Admin interface. It performs two operations:
 * 1. Deletes all rows from a predefined list of statistics tables (and their
 *    `*_reset` counterparts).
 * 2. Executes `VACUUM` on the statistics database to reclaim space.
 *
 * The function respects the `variables.vacuum_stats` setting: if `false`,
 * the function returns immediately without performing any operation.
 *
 * @param is_admin If `true`, operate on the `stats` schema within the admin
 *                 database (`stats.*` tables). If `false`, operate on the
 *                 standalone statistics database.
 *
 * @note The list of tables includes both MySQL and PostgreSQL statistics
 *       tables, even when the trigger is a MySQL-specific `TRUNCATE`. This
 *       ensures statistics are fully cleared regardless of the protocol that
 *       initiated the operation.
 *
 * @warning The table `stats_pgsql_stat_activity` is explicitly excluded from
 *          the deletion list because it is defined as a SQL VIEW (see
 *          `STATS_SQLITE_TABLE_PGSQL_STAT_ACTIVITY`). Attempting to `DELETE`
 *          from a view would cause a SQLite error:
 *          `"cannot modify stats_pgsql_stat_activity because it is a view"`.
 *          The view is based on `stats_pgsql_processlist`; clearing the
 *          underlying table automatically clears the view's content.
