- move startup message from controllers to the Application classes (SpringBoot configuration beans)
- added static imports for most static variables and static methods
- simplified a few nested *if*s
- replaced Arrays.asList() with explicit immutable collections
- fixed a few IntelliJ code inspection warnings
