chore(sql): 新增 all_tables.sql 完整数据库表结构

新增文件：
- all_tables.sql: 包含所有21个表的完整SQL脚本
  - 基础模块: users, documents, elements, annotations, graphs, parse_tasks, sessions
  - 图谱模块: graph_nodes, graph_relations
  - 补充模块: rules, data_sources, text_storage
  - RAG模块: text_chunks, vector_embeddings
  - 文档结构化: document_blocks, document_entities, document_elements
  - 模板系统: templates, source_files, variables, generations

rebuild_all.sh 更新：
- 新增 --simple 选项：使用 all_tables.sql 单文件初始化
- 适合新环境快速部署
