* fix test server setup:
- go map access is not deterministic
- this can lead to a route: /foo/bar/1 matching /foo/bar before matching /foo/bar/1 if the map iteration go through /foo/bar first since the regex match wasn't bound to start and end anchors
- registering handlers now converts * in routes to .* for proper regex matching
- test server route handling now tries to fully match the handler route
* add missing /v1 prefix to fine-tuning job cancel test server handler
* feat: implement new fine tuning job API
* fix: export ListFineTuningJobEventsParameter
* fix: lint errors
* fix: test errors
* fix: code test coverage
* fix: code test coverage
* fix: use any
* chore: use url.Values
