fix: match URL-encoded newlines in rest route params

[Conduitry]

Rest route params currently cannot match newline characters (or %0A, a URL-encoded newline character). This is because in regexes, . does not match a newline.

This PR adjusts the regexes created for rest route params to use [^] instead. It adjusts existing unit tests and adds a couple more. Note that we use actual newline characters in the unit tests (rather than %0A) because by the time the exec() function is called in real applications, the URL has already been decoded.
