feat: 新增增量索引接口并重构索引接口命名

新增功能： - 新增 POST /indexer/index 增量索引接口，支持按SPU ID列表进行增量索引 - 新增 indexer/indexer_logger.py 索引日志模块，统一记录全量和增量索引日志到 logs/indexer.log（JSON格式） - IncrementalIndexerService 新增 index_spus_to_es 方法，实现增量索引功能接口重命名： - POST /indexer/bulk -> POST /indexer/reindex（全量重建索引） - POST /indexer/incremental -> POST /indexer/index（增量索引） - POST /indexer/spus -> POST /indexer/documents（查询文档）日志系统： - 全量和增量索引操作统一记录到 logs/indexer.log - 记录请求参数、处理过程、ES写入结果、成功/失败统计等关键信息 - 支持按索引类型、租户ID、SPU ID等维度查询日志文档更新： - 更新接口文档，包含新的接口命名和增量索引接口说明 - 添加日志查询示例（grep和jq两种方式）

+
+#### 与 `/indexer/index` 的区别
+
+| 接口 | 功能 | 是否写入ES | 返回内容 |
+|------|------|-----------|----------|
+| `/indexer/documents` | 查询SPU文档数据 | 否 | 返回完整的ES文档数据 |
+| `/indexer/index` | 增量索引 | 是 | 返回成功/失败列表和统计信息 |
+
+**使用场景**：
+- `/indexer/documents`：用于查看、调试或验证SPU数据，不修改ES索引
+- `/indexer/index`：用于实际的增量索引操作，将更新的SPU数据同步到ES
