Sequencer web doesn´t show progress on cat_B cal and tailcut sgeneration

[contrera]

Right now, three different sequencers are running, plus the GainSelection pass. Sequencer_web produces a web page with the advance of sequencer_1 and sequencer_2, but not of sequencer_tailcuts, so we are in the dark in this part of the processing.
- We need to include tailcuts+cat-B generation info in the sequencer panel.
- It would be nice to add also Gain_Selection to have a single panel
