Restore M365Connector.delete_message (was an orphaned method body)

The def line for delete_message had been lost, leaving its body as
unreachable dead code at the end of _delete() and no delete_message
attribute on the connector. Deleting an Outlook message therefore failed
with "'M365Connector' object has no attribute 'delete_message'". Restored
the method (soft-delete: move to Deleted Items, fall back to DELETE).

 - **Cache invalidation** — `invalidateHistoryCache()` clears `_sessions` and `_latestRefScanId`. All three `*_done` SSE handlers call `window.invalidateHistoryCache?.()`.
 - **Re-scan diff** — items present in the previous session but absent from the current one are tagged `_resolved: true`, rendered with `.card-resolved` and a green ✓ badge, and NOT added to `S.flaggedData` (grid-only, cannot be bulk-selected or exported).
 - **Mode transitions** — `startScan()` calls `window.exitHistoryMode?.()` before clearing the grid.
+- **`renderGrid(files)` hides the landing cards** — whenever `files.length > 0` it hides `#emptyState` and `#lastScanSummary` and shows `#grid`. This is centralised here because the live `scan_file_flagged` handler (`scan.js`) shows the grid but does NOT clear those panels, so results would render *underneath* a still-visible landing/last-scan card until a manual refresh. Do not move this hiding back into individual callers — every render path (live SSE, `loadOpenItems`, history, filters) must clear the landing. The empty case (`files.length === 0`) is left untouched so callers still control the empty/landing state.
