Self-review (Task 16) follow-up fixes:
- PdoEventRepository::recent(): add event_id DESC as a secondary sort key
after occurred_at DESC so ties (equal device-reported timestamps) resolve
deterministically, matching InMemoryEventRepository's insertion-order
tie-break.
- PdoZoneRepository::updateOwned(): after the ownership-scoped UPDATE,
disambiguate a 0-rowCount() result (MySQL reports "changed" rows, not
"matched" rows) with a targeted existence check, so a genuine no-op
resubmit (identical level/polygon) still succeeds while a zone deleted
concurrently between the ownership check and the UPDATE now throws
instead of save() silently reporting success for a zone that no longer
exists.
Full suite still green: 59 tests, 114 assertions, 4 skipped, 0 failures,
0 warnings/deprecations.
