- seperated tool result queries and db operations into two distinct functions. This enables us to use coroutines in the query function and be synchronous (transactional) for the db operation
- Transactional statements rely on EnableAspectJAutoProxy annotation, which was previously missing
- added locktypes to repository interfaces
- now mainly using transaction propagation type REQUIRED to create a new transaction (this is more a backup since we should always have a transaction due to the annotations in the controllers)

fix: OrtJson can be null, was unhandled

See merge request !50

fix: database connection handling and KPI database format

See merge request !49

- KPIEntity no longer depends on an enum value from the SPHA library. This change should result in a more robust and predictable code behavior against changes in the library.
- database operations now take a dispatcher as an input to enable automated testing
