Non-UUID keyid in /apikeys path causes incorrect responses for GET, DELETE, and POST in apikey endpoint

[wenyang-cao]

when {keyid} is not a valid UUID type (e.g., /apikeys/abc123):

• GET and DELETE routes fail to match path(JavaUUID), and fall back to 405: supported methods: POST
• POST /apikeys/abc123 is incorrectly matched to*POST /apikeys, since Akka HTTP does not reject the extra path segment unless explicitly constrained → leading to successful 201 OK responses
