feat: 使用banana模型生成分镜图片，修复数据库列类型问题

- 修改RealAIService.submitTextToImageTask使用nano-banana/nano-banana-hd模型
- 支持根据hdMode参数选择模型（标准/高清）
- 修复数据库列类型：将result_url等字段改为TEXT类型以支持Base64图片
- 添加数据库修复SQL脚本（fix_database_columns.sql, update_database_schema.sql）
- 改进StoryboardVideoService的错误处理和空值检查
- 添加GlobalExceptionHandler全局异常处理
- 优化图片URL提取逻辑，支持url和b64_json两种格式
- 改进响应格式验证，确保data字段不为空
