v1.3.1 - the first icon moves now

Both issues from live play, same session:

1. FIRST ICON NEVER CHANGED. The simulation bailed out whenever aura data was flagged degraded - and Midnight hides aura data in combat, so it bailed out on essentially every pull. The bar then fell back to Blizzard static pick, which never moves. Energy, combo points and cooldowns are all still readable in combat and drive most of the priority list, so the simulation now runs regardless and simply lowers its confidence when buffs are hidden. Icon 1 is now the next step of YOUR sequence.

2. KEYBINDS ON ONLY SOME ICONS. The action-slot to binding map covered slots 1-12 and 61-72 and mislabelled everything above 73, so an ability on most bars resolved no keybind at all. Replaced with the full canonical slot mapping (all bars, including the paged main bar).

129 tests, three consecutive clean runs.
