- Prevent Automation UI from overriding schedule:
- mapDbScheduleToUi now parses intervals robustly (cron/duration/seconds) via parseInterval
- mapUiScheduleToDb merges with existing config and stores interval as seconds (no lossy cron conversion)
- /api/config passes existing scheduleConfig to preserve ENV-sourced values
- schedule-sync endpoint uses parseInterval for nextRun calculation
- Add AUTO_MIRROR_REPOS support and scheduled auto-mirror phase:
- scheduleConfig schema includes autoImport and autoMirror
- env-config-loader reads AUTO_MIRROR_REPOS and carries through to DB
- scheduler auto-mirrors imported/pending/failed repos when autoMirror is enabled before regular sync
- docker-compose and ENV docs updated with AUTO_MIRROR_REPOS
- Tests pass and build succeeds
