test(browser-integration): Add sentry DSN route handler by default

[mydea]

Instead of sprinkling this through tests, we can just generally handle this route, streamlining tests a bit and avoid unexpected errors/console warnings messing with things.

So this PR basically inverses this - by default, we add a "success" route handler for the Sentry DSN, and if you want to have special handling you can opt-out of this.
