chore(grouping): Differentiate fingerprint and enhancements class names

[lobsterkatie]

Both fingerprinting rules and stacktrace rules ("enhancements") use classes called Rule and Match, and without spending time figuring out the context, it's hard to tell which of them one is dealing with. This therefore changes the names all four classes (along with the enhancements Action class, just to keep things standardized) to include Fingerprint or Enhancement as appropriate. No behavior changes, just a lot of find and replace.
