[Uptime] Change API access to new authz authorization paradigm

[jasonrhodes]

Authorization for API endpoints must be migrated away from the previous use of options.tags: ["access:some_tag"] and replaced with a new security.authz object. Information can be found here: https://docs.elastic.dev/kibana-dev-docs/key-concepts/security-api-authorization

Note: this should not be confused with the options.access value that is still used to indicate whether an API route is internal or public.

Mostly covered in this PR and now it's completed by this one

Thanks, @fkanout -- I was under the impression that everything mentioned in this issue was not able to be auto-migrated and required us to manually migrate, not sure why this isn't the case (it creates extra work and distraction for us, unfortunately). I've asked about it here.
