Clean up dependencies in uui-server

Clean up dependencies in uui-server

- remove msb-java-sdk since msb is not used in the java code
  (and it has lots of outdated transient dependencies)
- change scope of junit, mockito and powermock dependencies to test
- do not pin spring framework version as it is already managed by spring-boot dependency management [0]
- replace spring-boot-starter-data-rest with -web since the former bundles the latter and actually nothing
  of -data-rest is used in the codebase
- update jacoco plugin to be compatible with Java 17

[0] defining a separate version also bears the risk of incompatability between the two
