### Fixed - **Cards not shown after browser refresh** — when the browser reconnected to the SSE stream after a completed scan, the scan_phase events in the replay buffer temporarily set S._m365ScanRunning = true (all running flags start at false after a page reload). The watchdog's loadHistorySession call fired in this window and bailed on the stale flag; once scan_done cleared the flag, _initialStatusChecked was already true so loadHistorySession was never retried. Fixed by having the sse_replay_done handler retry loadHistorySession(null) when no scan is running and S._historyRefScanId is still null after replay.
