[Issue] Fuel-Air insta-kill result display is confusing

[ManoftheSea]

Brief Description *

I dropped the bomb on multiple infantry, and saw this in the report:
Fuel-air weapon against infantry may result in automatic destruction. Needs 9-, rolled 6 [4 + 2] (2d6) + 2 (distance from blast center) : destroyed!
Fuel-air weapon against infantry may result in automatic destruction. Needs 9-, rolled 9 [7 + 2] (2d6) + 2 (distance from blast center) : destroyed!

I initially understood this to be that the first roll was a six plus two and the second a nine plus two. Digging into the underlying rolls, it turns out the first actually rolled a [3, 1] and the latter a [2, 5]. This was surprising in two ways:

• The first roll added 1 to each die, the second roll added 2 to one and 0 to the other.
• The grouping of the terms looks like "total-rolled [rolls] (dice) modifier", but it's actually "TN, total [modified rolls] (dice) modifiers"

It seems like the use of a "less than or equal" target is already weird. But I would have expected the UI to say "Needs 8; rolled 7 : destroyed", where 8 is underlined and brings up the explanation of 10 (fuel-air save) - 2 (range) and 7 shows range [1-6], result: 7, rolls 2,5.

3. Steps to Reproduce

1. put infantry on the board
2. fire fuel-air munitions too close to them (here, 2 hexes away)
3. read the report
