fix(backend): switch to sentry-spring-boot-4:8.41.0 for Spring Boot 4/SF7 compatibility

sentry-spring-boot-starter-jakarta 8.5.0 does not support Spring Boot 4.0 —
it logs an "Incompatible Spring Boot Version" warning and its SentryAutoConfiguration
crashes SF7 bean-name generation. sentry-spring-boot-4 (added in 8.21.0) is the
dedicated Spring Boot 4 module with a fixed auto-configuration class.

- Replace sentry-spring-boot-starter-jakarta:8.5.0 with sentry-spring-boot-4:8.41.0
- Delete SentryConfig.java — workaround no longer needed, auto-config handles init
- Remove spring.autoconfigure.exclude from application.yaml + application-test.yaml
- Delete SentryConfigTest.java — tested the deleted workaround class
- Update ApplicationContextTest: assert Sentry.isEnabled() is false when no DSN set
