Summary
https://jsw.ibm.com/browse/MASCORE-7537

Mirrors the existing Manage and Facilities ReplicaDB wiring for Monitor in the gitops-mas-apps pipeline. Pipeline-only change; no CLI function or template changes.

Changes
tekton/src/pipelines/gitops/gitops-mas-apps.yml.j2

• Added replica_db_monitor and manually_set_enhanced_hadr_monitor pipeline params (default "false")
• gitops-rds-db2-database-monitor: pass replica_db
• gitops-db2u-database-monitor: pass replica_db and manually_set_enhanced_hadr
• Added gitops-db2u-replica-database-monitor (is_replica_task: 'true', runs after the primary), matching the Manage and Facilities replica tasks

Not in scope

• enable_db2_read_replica in the RDS Terraform template stays hardcoded to false, as for Manage and Facilities

Testing

• End-to-end: created the Monitor in-cluster (db2u) primary and -sdb DB2 instances on a dev cluster; both Db2u database pods Running and Ready, HADR in PEER / CONNECTED, and the -sdb application Synced and Healthy in Argo CD
• Tested with quay.io/ibmmas/cli:23.21.0-pre.mascore-7537 (this branch's build) set on the db2u-database task in a saas-tekton test branch

• Not tested: RDS path with a real AWS replica
