[Bug] API inconsistencies

Is this a support request?

Is there an existing issue for this?

• [X] I have searched the existing issues

Current Behavior

I am finding some bugs in the API responses, especially:

• calling /api/v1/node/<nodeId> does not return validTags although tags are present, calling /api/v1/node and getting the node I want, validTags is properly populated
• registerMethod is always REGISTER_METHOD_UNSPECIFIED even if in the DB the nodes have the correct value for the register method

Expected Behavior

I would expect that a call to /api/v1/node/<nodeid> would return the correct set of tags and that the registerMethod would be set to the correct value

Steps To Reproduce

Do an API call to /api/v1/node/<nodeid> and inspect the response

Environment

- OS: docker
- Headscale version: v0.23.0-alpha12
- Tailscale version: not relevant

Runtime environment

• [ ] Headscale is behind a (reverse) proxy
• [X] Headscale runs in a container

Anything else?

No response

/api/v1/node/backfillips fails, I think that the route is not matched, so it tries to retrieve info on node with id backfillips, failing, of course

for what it is worth, I've tested this and it worked: "nodes":[{"id":"1","machineKey":"mkey:1538e343afbf96495e98bf98385c2d14254c682ec71436ed1a294f1f21100c63","nodeKey":"nodekey:f5ab18e3dde949988ec6fdcf31c42ec1440cd96d6d77c7048f725fba2003f869","discoKey":"discokey:16ef4ff594f66440486015c341c64d3b414b922f84e1d1635e31958286bf684b","ipAddresses":["100.64.0.1","fd7a:115c:a1e0::1"],"name":"Veeam","user":{"id":"1","name":"boz","createdAt":"2024-07-17T06:22:27.041754446Z"},"lastSeen":"2024-07-17T06:24:42.982663920Z","expiry":"0001-01-01T00:00:00Z","preAuthKey":null,"createdAt":"2024-07-17T06:24:38.276313596Z","registerMethod":"REGISTER_METHOD_CLI","forcedTags":[],"invalidTags":[],"validTags":[],"givenName":"veeam","online":true}]}
