fix: Re-apply JPA repository configuration and revert to update mode (#110)

- Add @EnableJpaRepositories to KoreaTravelGuideApplication to explicitly scan JPA repositories
- Remove duplicate @EnableCaching and @EnableRedisRepositories from RedisConfig
- Change ddl-auto from create to update after database schema reset
- Fixes Redis Repository warning logs by properly separating JPA and Redis repository scans

This re-applies changes from PR #107 that were overwritten by PR #109.
