fix: increase temp addr TTL to allow long chains to ingest

[alanshaw]

After about a day, ingestion stops with the following error:

2026-03-01T15:56:36.551Z ERROR indexer/ingest ingest/ingest.go:1168 Error while ingesting ad. Bailing early, not ingesting later ads. {"publisher": "12D3KooWLrikEsjt5wz326bRhCyEThRhJ936o13c5Ej7ttLbkxgp", "worker": 5, "adCid": "baguqeerabpdnzprfib2wsgjb2lbss5wec4n33b6itkgwyechxponl6ohtf2q", "err": "syncEntriesErr: failed to sync first entry while checking entries type: cannot create ipni-sync handler: no peer addrs and none found in peertore", "adsLeftToProcess": 2809436}

It correlates with memory usage dropping when the error occurs - signaling that the ingestion has been abandoned.
