btn_pot_reset always reset the simulated Pot to the ambient temperature. Add doubleSpinBox_pot_temp next to it (shown/hidden together, same as the button) so the user can dial in a different starting temperature before committing it - it seeds from the same remembered ambient value on startup but is otherwise independent and not persisted. tasks/pot.py's PotTask.recv() now resets the plant to whatever temperature the 'Reset' message carries, falling back to ambient for the bare True a caller might still send.
