feat: remove EntityManager from DefaultTrackerBundleService [DHIS2-21378]

[enricocolasante]

Summary

Phase 5 of the tracker import Hibernate → JDBC migration (DHIS2-21378). Replaces the updateTrackedEntitiesLastUpdated named native query — the last Hibernate dependency in DefaultTrackerBundleService — with a direct
NamedParameterJdbcTemplate call, and removes the now-unused @NamedNativeQuery annotation from TrackedEntity.

• DefaultTrackerBundleService: the EntityManager field and the org.hibernate.Session / jakarta.persistence.EntityManager imports are gone; a NamedParameterJdbcTemplate is injected via the Lombok-generated constructor. The bulk UPDATE on trackedentity
  still partitions by 20k UIDs and still casts lastupdatedbyuserinfo as jsonb. UserInfoSnapshot is serialised once per postCommit() call instead of once per partition.
• TrackedEntity: @NamedNativeQuery("updateTrackedEntitiesLastUpdated", ...) and the jakarta.persistence.NamedNativeQuery import are removed — no other call site referenced this query.
• No behaviour change beyond the persistence-layer swap: same SQL, same parameters, same partition size.

Next steps

• Quick fix ✅ formatDate: SimpleDateFormat → static final DateTimeFormatter
• Phase 0 ✅ Remove EntityManager from TrackerPersister interface and all method parameters — feat: remove EntityManager from TrackerPersister [DHIS2-21378] #23797
• Phase 1 ✅ Decouple ChangeLogAccumulator from Hibernate Session — feat: decouple ChangeLogAccumulator from Hibernate Session [DHIS2-21378] #23836
• Phase 2 ✅ Extract FileResource assignment update into FileResourceStore — chore: Extract FileResource assignment update [DHIS2-21378] #23879
• Phase 3 ✅ Introduce EntityWriteBatch; accumulate and batch-flush TEAV writes — feat: stage TEAV writes through EntityWriteBatch [DHIS2-21378] #23970
• Phase 4 (4b only) ✅ Stage top-level entity inserts and updates through EntityWriteBatch — feat: Batch entity when persisting [DHIS2-21378] #24005
• Phase 5 👈 this PR — Replace updateTrackedEntitiesLastUpdated named query with NamedParameterJdbcTemplate; remove last Hibernate dependency from DefaultTrackerBundleService
• Phase 4a + Phase 6 — Pre-allocate IDs from PostgreSQL sequences and swap the EntityWriteBatch.flush() Hibernate delegation for JDBC multi-row INSERT / unnest UPDATE, one entity type at a time. (Phase 4a does not ship alone: with @GeneratedValue(SEQUENCE),
  Hibernate 6 rejects a pre-assigned non-zero id on em.persist, so pre-allocation lands together with the JDBC INSERT for the same entity type.)
