v3: climate control slider is unusable

The problem

With web interface v3, the Climate/PID UI is crammed into too small a space. Because of this, the setpoint slider has not enough space to actually slide. Whenever you drag the slider, it'll set to its lowest point because there is not a single pixel of space left to drag it to the right.

Related: the crammed-together layout makes it hard to read. In the above screenshot, it's not set to 405° but to 40° -- the other 5 is for the 5-20 slider.
