stability and race conditions in auth and node store (#2781)
This PR addresses some consistency issues that was introduced or discovered with the nodestore.

nodestore:
Now returns the node that is being put or updated when it is finished. This closes a race condition where when we read it back, we do not necessarily get the node with the given change and it ensures we get all the other updates from that batch write.

auth:
Authentication paths have been unified and simplified. It removes a lot of bad branches and ensures we only do the minimal work.
A comprehensive auth test set has been created so we do not have to run integration tests to validate auth and it has allowed us to generate test cases for all the branches we currently know of.

integration:
added a lot more tooling and checks to validate that nodes reach the expected state when they come up and down. Standardised between the different auth models. A lot of this is to support or detect issues in the changes to nodestore (races) and auth (inconsistencies after login and reaching correct state)

This PR was assisted, particularly tests, by claude code.

Integration testing

Headscale relies on integration testing to ensure we remain compatible with Tailscale.

This is typically performed by starting a Headscale server and running a test "scenario" with an array of Tailscale clients and versions.

Headscale's test framework and the current set of scenarios are defined in this directory.

Tests are located in files ending with _test.go and the framework are located in the rest.

Running integration tests locally

The easiest way to run tests locally is to use act, a local GitHub Actions runner:

act pull_request -W .github/workflows/test-integration.yaml

Alternatively, the docker run command in each GitHub workflow file can be used.

Running integration tests on GitHub Actions

Each test currently runs as a separate workflows in GitHub actions, to add new test, run go generate inside ../cmd/gh-action-integration-generator/ and commit the result.
