Update the purge tests for PurgeSummary.

purge_archived returns a PurgeSummary, but the tests still compare the result directly with an integer. Update the assertions to use .deleted and validate .cutoff.

Suggested fix 
-    assert deleted == 1
+    assert deleted.deleted == 1
+    assert deleted.cutoff == NOW - timedelta(days=30)
...
-    assert deleted == 1
+    assert deleted.deleted == 1
+    assert deleted.cutoff == NOW - timedelta(days=30)
...
-    assert await purge_archived(test_db, retention_days=30, now=NOW) == 0
+    summary = await purge_archived(test_db, retention_days=30, now=NOW)
+    assert summary.deleted == 0
+    assert summary.cutoff == NOW - timedelta(days=30)
...
-    assert deleted == 1
+    assert deleted.deleted == 1
+    assert deleted.cutoff == NOW - timedelta(days=DEFAULT_RETENTION_DAYS)

Review comment at @backend/app/jobs/purge_archived.py at line 47:
Update the tests for purge_archived to assert against the returned PurgeSummary:
check its deleted count and cutoff in each case, using the relevant retention
period to calculate the expected cutoff.
