feat(startup): 服务端启动 bootstrap 与缓存预热

- 新增 STARTUP_BOOTSTRAP_ENABLED / STARTUP_CACHE_WARMUP_ENABLED 配置开关
- lifespan 拆分 bootstrap 步骤并后台线程预热缓存，失败可降级继续启动
- server_start.sh / web_start.sh 扩展 SERVER_PORT、启动与调度开关的 env 覆盖
- bootstrap_paddleocr_mobile.sh 改用 python3 并补充 poppler-utils 依赖
- 补充启动 bootstrap 与 env 覆盖优先级测试
