Extend SAM Range to cover Hydros when stacked (#2351)

## Description:

Implements SAM range extension for stacked SAMs to cover hydros as
requested in #2347 and many times from users in discord.
This implementation is as simple as possible: At level 5 and higher,
SAMs extend their range to the range of a hydrogen bomb + 10 for a small
safety margin. Levels 2-4 are interpolated between.

Screenshot to show the sizes compared to a hydro:

/>

Everything works together with the new range UI, although I might need
to unify with / rebase on #2350. Not yet tested with #2348, but
shouldn't be an issue.

## Input needed:
- Should I add tests for this?
- This is in effect a massive buff to SAMs, might be too strong. Popular
ideas / suggestions from Discord to balance things:
  - Cap the SAM upgrade level at the maximum range (easy to do)
- Alternative, instead of capping the level, decrease the range when
missiles are reloading
- Increase the cost scaling for SAMs per stack, and scale way higher
(e.g. 1.5M > 3M > 4.5M > 6M or something like that) (UI integration
unclear, breaks with existing cost logic)
  - Decrease SAM hit probability for Hydros

I'm happy to implement any of these paths, or just roll with the simple
way it's set up now, just let me know.

## Please complete the following:

- [x] I have added screenshots for all UI updates
- [x] I process any text displayed to the user through translateText()
and I've added it to the en.json file
- [x] I have added relevant tests to the test directory
- [x] I confirm I have thoroughly tested these changes and take full
responsibility for any bugs introduced

## Please put your Discord username so you can be contacted if a bug or
regression is found:
