[FIX] web: format value of statinfo widget

The value of the statinfo widget is rendered by the qweb after a t-esc.
Say if the python rounding returned 14.0000000001
(supposed to be a two digits precision number through the magic of floats)
then the statinfo widget would print it as-is.

We now format the value at assignation.
