[IMP] mrp: display Ready to Produce qty in MO Overview Report

Before this commit
==================
Currently, There is no way to know how many qty users can produce with the current stock.

After this commit
=================
With this commit, In the MO Overview report, the following stages are added:
'Ready', 'Not Ready', and '{X} Ready'. the Ready to Produce qty is based on
the component reserved quantity + component free quantity. Furthermore, the
table header in the MO status overview report has been slightly highlighted for
improved visibility.
