Implement apix-registry with IoT sunset/decommission lifecycle and full BDD suite

- REST API: register, patch, O-level, replacements, history, search endpoints
- IoT lifecycle validations: future sunset, lock-before-release, sunset-passed-before-decommission
- DB schema: Liquibase changesets 001–008 (services, versions, replacements, sunset-at column)
- @ColumnTransformer(write="?::jsonb") on bsm_payload fields to avoid JDBC varchar→jsonb rejection
- Jandex plugin on apix-common + quarkus.index-dependency so @NotBlank validators resolve at runtime
- quarkus-logging-json extension added; quarkus.log.console.json=false is now a recognised key
- Fix requireSunsetBeforeLockRelease: Boolean.TRUE.equals instead of !Boolean.FALSE.equals (null guard)
- BDD suite: 27 scenarios / 213 steps across 5 feature files (sunset-lock, decommission, replacement, discovery, anonymity)
- Test infrastructure: JDBC TRUNCATE in @Before for DB isolation, Arc.container() for clock control — no test endpoints in production code
- sunsetAt truncated to microseconds in BDD steps to match Postgres timestamptz precision
- Cucumber step fixes: singular/plural candidate(s), lastResponse propagation in replacementsReturnsNCandidates
