Universal search for Jedox

Add a universal search ("search everywhere") dialog in Jedox Web, that allows to search across a large stack of objects, and then navigate to a specific result; sort of similar e.g. to "Spotlight" feature on MacOS.

Possible objects to search for: Reports (in Designer and Reports panel), Integrator projects, Modeller (database names, cube names, dimension names, maybe element names), user names, group names, etc

Result list should offer navigation capabilities. For some objects, it might be helpful to even offer multiple options (e.g. cubes: open cube in modeler, open paste view on the cube...), although we shouldn't overblow it and keep result list simple and "parse-able".

A possble extension is to allow prefixing, so user could already restrict which objects to search for, e.g. "cube:..." or "user:..."
