fix: 修复启动和运行时错误

1. 修复 Neo4j 条件注解
   - @ConditionalOnBean(Driver.class) 改为 @ConditionalOnProperty
   - 确保 neo4j.enabled=false 时不加载相关 Bean

2. 修复 SQL 字段名不一致
   - Repository 中 created_at/updated_at 改为 create_time/update_time
   - 与 SimpleModel 基类和数据库表结构保持一致

3. 开放开发阶段 API
   - /auth/**, /api/v1/documents/**, /api/v1/graph/** 等接口暂时开放
   - 便于开发测试

影响文件：
- Neo4jGraphController, Neo4jGraphService, Neo4jNodeRepository, Neo4jRelationRepository
- GraphNodeRepository, DocumentEntityRepository, TemplateRepository, DataSourceRepository, RuleRepository
- SecurityConfig
