Subject: [PATCH] fix(backend): explicit Flyway bean to bypass broken
 auto-configuration
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Spring Boot 4.0 Flyway auto-configuration is not triggering in the CI
environment — confirmed by empty DB and no flyway_schema_history table.
Replace YAML-based auto-config with an explicit @Bean that creates and
runs Flyway directly on startup, independent of any auto-configuration
conditions. Disable the auto-config via spring.flyway.enabled=false to
prevent interference. Add @DependsOn("flyway") to DataInitializer to
enforce that CommandLineRunner beans are only registered after migrations.
