Add the target system's name to the ARIA labels for the buttons used to move ships within Andromeda. Which is to say, the labels now indicate the system a ship will be removed from or added to. For example, "Add Scout Ship to Gorddon System" or "Remove Dreadnought from Chthonian". The labels also now use the proper names of the ships instead of their internal identifiers.
The current controls for Andromeda ships are confusing when navigating with a screen reader, since it's supposed to visually be a grid (I believe). The changes in this commit improve things, at least during my testing. 1. `is-sr-only` h4 elements are placed before the columns of each ship type with movement controls. 2. Another `is-sr-only` span is added after the h4 elements to better signify that the next number represents the count of that type of ship in the Gateway System. 3. The column consisting of available systems is now hidden using "aria-hidden", as it was simply read as a list of names and was therefore unhelpful for screen readers.

The current controls for Andromeda ships are confusing when navigating with a screen reader, since it's supposed to visually be a grid (I believe). The changes in this PR improve things, at least during my testing. All changes only change the aria or the contents of "is-sr-only" elements, so I am pretty sure nothing changes visually.
