feat: add scheduled jobs, OA fetch and NCC push automation

- Add DB-driven scheduled jobs (av_scheduled_job / av_job_run, V5) with
  editable cron, manual trigger, 7-day run history and startup recovery
- Add OA document fetch job: configurable HTTP client (no redirects),
  incremental watermark, per-document failure isolation, mock seed fallback
- Replace fixed-rate NccPushJob with NccPushRunner/NccPushHandler driven
  by the scheduled job
- Add sys_config management (V3/V4) with secret masking and metadata-only
  audit
- Add LLM-powered account suggestion, expense context and line feedback (V2)
- Update CORS defaults for workspace proxies; add tests for new components

+            5. ruleHint 只是规则引擎的提示，不是强制结果，可以结合上下文选择其他候选科目。
+            6. confidence 是 0 到 1 之间的小数，表示科目选择的把握；没有把握时不要给出高置信度。
