Complete the ClickHouse migration by removing all PostgreSQL analytics code. PostgreSQL now serves only RBAC, config, and audit — all observability data is exclusively in ClickHouse. - Delete 6 dead PostgreSQL store classes (executions, stats, diagrams, events, metrics, metrics-query) and 2 integration tests - Delete RetentionScheduler (ClickHouse TTL handles retention) - Remove all 7 cameleer.storage.* feature flags from application.yml - Remove all @ConditionalOnProperty from ClickHouse beans in StorageBeanConfig - Consolidate 14 Flyway migrations (V1-V14) into single clean V1 with only RBAC/config/audit tables (no TimescaleDB, no analytics tables) - Switch from timescale/timescaledb-ha:pg16 to postgres:16 everywhere (docker-compose, deploy/postgres.yaml, test containers) - Remove TimescaleDB check and /metrics-pipeline from DatabaseAdminController - Set clickhouse.enabled default to true Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
