LDEV-3971: Remove pointless synchronisation from Java methods. It would not work in multi-node environment anyway. Focus on DB transactions. General clean up and formatting.
LDEV-3765: Add command websockets in all tools. Run check less often (5s vs 2s) as the effect does not need to be immediate. Reorganise code. Add i18n support.
LDEV-3660: Remove export potfolio resources: Java classes, JPS, DB entries and labels. Remove localLinkPath attribute from CSS tag as it was only used for export portfolio.
