Lump Harbormaster build steps into groups
Ref T8089. We have a lot of broken/confusing/prototype build steps that I want to hide from users when we unprototype Harbormaster.
The dialog is also just kind of unwieldy.
Organize this UI a little better and put all the sketchy junk in a "prototypes" group that you can't see unless prototypes are enabled.
This doesn't break anything (the old steps will still work fine), but should reduce user confusion.
New UI (prototypes off):
