nit: Could we rename all private properties to consistently follow the hash-prefix naming scheme?
The hash prefix is enforced by JavaScript at runtime on the syntax level, whereas the scope keywords public/protected/private are compile-time syntactic sugar that aren't enforced (we also find it unnecessary to use the public keyword for this reason).

I considered this during the refactor, but the problem we have is that we need to spy on "internal" methods for testing purposes. So I cannot completely enforce privacy at runtime (at least not at the moment).
The best compromise i found was to label methods as private or public so we can check this with TypeScript.
Ideally we should redesign the controller data flow so we care only about public methods output and test only that. But for now this involves work that goes a bit out of the scope of this migration to BaseController V2

Oh you're right looks like there are quite a few of those spyOn calls. I'm good with refactoring the tests in a separate ticket.

Probably out-of-scope for this PR, but since this controller contains polling logic, could it be refactored to inherit from StaticIntervalPollingController in the future?

Thanks for the heads up! I didn't know we had that. I see that TokenDetectionController is using it this way also. Like you said, i consider this a out of scope for this PR, but will definitively will add this on our to-do list

Do we need to keep this here?

its part of the todo list, kept it as a comment so the linter does not complain, but i did want to keep those values around for when we refactor to extend the polling functionality from StaticIntervalPollingController

Does this need to be finished?

not on this PR, the current design involves testing functionality that should be internal. ideally we need to separate internal logic from the public one, and only test methods that we expose as public. for this a much bigger refactor is needed and i already added a jira task for that

Description
This PR refactors SwapsController so it extends from BaseController (v2). This refactor also involves migrating the current set of unit tests to Typescript

Fixes:
Manual testing steps
All tests are in the green, but the best approach would be test swaps manually end to end.
