feat(admin): «اجرت» screen — edit the making-charge formula, check a sample, approve

The formula shown as a sentence with coloured terms; each term can be
switched off or given a coefficient; promotion as largest or sum; a
constant, floor, cap and rounding. A sample order line is computed by
the server for the formula in force and the draft side by side, changes
highlighted. Saving needs a change, a confirmed sample and a final
confirm; the approved sample is kept and shown as the formula's
reference, with earlier versions below.
