fix: format Decimal values for display in content evaluator

[developerfred]

• Apply toFixed(2) to relevance and reward calculations to ensure consistent decimal place display.

Resolves #77

[0x4007]

It should only be once at the end. Which is the last time possible to set fixed?

[developerfred]

Yes, we must define in the last element, if it is number or float, in this case I focussed only on the rewards

I don't think using fixed numbers is the solution, since we would lose precision on calculations. The result given showed that numbers have been used over decimals which induced a floating precision loss on division (in the example it is literally doing 54.6 / 1). The fix is to properly use decimals during these operations.

Thanks, I will use this solution.
