There are boundary conditions that implement constant heat-flux in OpenFOAM. If your heat-flux has no spatial or temporal distribution then I'd recommend using these.
If you want to/have to use...

I'm not familiar with that solver. qMean is average in time or average in space as a function of time or space?

Depending on that timeVaryingMappedFixedValue might be able to help you

Currently no. Unless the data is a 1D-function q(s). Then you can use a lookup

I've explained it a number of times in different places: it is not THAT easy to do it in a general way (fileformats,...

That should work. Sign depends on your definition of the flux.

I usually limit myself to answers about the technical aspects of swak4Foam. Physics is your own responsibility

With "fractionExpression '0'" you're on the right track. What gradientExpression is supposed to to be depends on your physics (which heat-flux you want to prescribe). Rewrite it so that you get an...
