Fix meal plan removal ignored on first attempt after app launch

Guard reconcileFromServer() with a syncStartTime so that entries
modified locally during an active performSync() cycle are never
overwritten by stale server data. This prevents the race condition
where a user removes a meal plan entry while Phase 2 of sync is
still iterating server recipes.
