feat: scaffold Micronaut+Kotlin service per ACMA-8 v4 architecture

- 4 modules (ingress/processing/delivery/reference) + codec + infra + jobs
- Flyway V2.0.0: six aux tables (PROC_STATE/MSG_EVENT/REF_DATA/REQ_TRACK/PUMP_JOB/FLIGHT_STATE)
- Lua: snapshot_replace (atomic cover+gen-diff-delete), batch_delete (3:30 sweep)
- config: env-externalized secrets, phase A/B switch, ACMA-8 param-table defaults
- logback: logstash TCP JSON + traceId MDC
- pure-logic tests: identity (I3), schd aggregation max-by-EVENT_ID (FIX #7)
- build verified: gradle compile+test green on JDK 25 (Micronaut 5.1 requires JVM 25+)

Migrated from legacy repo subdirectory per repo-strategy decision (separate repo
per service, org convention). Refs: ACMA-9, ACMA-8 v4, ACMA-6
