Mobile: Map should fit better to Slovenia on initial load

[MarkoJuvancic]

The map shows too much of the rest of Europe on initial load.

On mobile it should be more zoomed out:

So we should basically use fitbounds leaflet's API to center and adjust zoom upon initial load.

Doing the same when searching to fit search results may have undesired effects as map bounds are also used as search parameters.

Desktop is fine, we could improve mobile (show whole Slovenia)

Also on full-screen desktop it would fit perfectly with one zoom level higher
