GUI: show estimated pot/water/grain mass on the step status line

Appends a "Pot: X kg, Water: Y kg, Grain Z kg, total W kg" breakdown to
the status bar's step line, using the pot_mass already in the loaded doc
(captured from Sud._parse_data(), previously discarded) and the current
step's already-resolved grain_mass/water_mass from self.sud_schedule.
