Issue
Ports the event-observing half of the charms' async replication module; the data plane landed in 2/8. Part of the stacked series — the promotion/standby flow methods land in 4/8.
Solution
PostgreSQLAsyncReplication(Object): constructor + observers on both replication relations, the public surface the charms consume (delegating to the manager),set_app_status/handle_read_only_mode, and the observed handlers_on_async_relation_joined(VM observesrelation_joined, K8srelation_created— divergence preserved),_on_async_relation_departed,_on_async_relation_broken(with the DPE-10203 teardown resilience: the standby check,update_configand watcher-endpoint failures are logged and survived),_on_async_relation_changed,_on_create_replication(clears a stale promotion before the guard, per #1913) and_on_secret_changed(by-id consumer matching via_same_secret_id).The
relationprobe treats a relation with unreadable databags as absent (DPE-10203).
