feat(db): add MySQL migrations 000001-000007 covering all 12 tables + seed [tsk_paiqu21eZIuw]

- 000001: users + devices（账户 / 设备，含 argon2id pw_hash、dp_uuid）
- 000002: plans + subscriptions（套餐口径来自 design/CLAUDE.md §7）
- 000003: code_batches + codes（SHA-256 code_hash，明文不入库）
- 000004: usage_daily + audit_log（最小数据原则 + JSON meta）
- 000005: providers + nodes（providers 先建，nodes FK 引用）
- 000006: node_events（9 值 ENUM）+ directory_version（CHECK id=1，MySQL ≥ 8.0.16）
- 000007: plans 三行 seed + directory_version(1,1)，ON DUPLICATE KEY UPDATE 保可重入

所有表 ENGINE=InnoDB DEFAULT CHARSET=utf8mb4，时间列 DATETIME(6)，
主键 BIGINT UNSIGNED AUTO_INCREMENT + 对外 uuid CHAR(36) UNIQUE。
每对 down 文件逆序 DROP（子表先于父表）。
