[wikimedia/fundraising/crm@master] Move logging of dedupe to deduper

https://gerrit.wikimedia.org/r/1214159

I'm having trouble determining the dedupe pair in question - I think it's cached in the prevnext table - I've put up a patch to try to output the pair being merged before the attempt starts to get the contact ID. I need to also check when the table is flushed....

echo '{"criteria":{"where":[["modified_date","BETWEEN",["2025-12-01 20:29:41","2025-12-01 21:29:41"]]]},"search_limit":0}' | wmf-cv -vv --in=json api Job.process_batch_merge
Entity: Job
Action: process_batch_merge
Params: {

"version": 3,
"criteria": {
    "where": [
        [
            "modified_date",
            "BETWEEN",
            [
                "2025-12-01 20:29:41",
                "2025-12-01 21:29:41"
            ]
        ]
    ]
},

• but if I change the time range by even 1 second it works - which makes me think the cached selection is the issue
