When we encounter a source we cannot resolve, we skipped the whole rule,
even if some of the srcs could be resolved. In this case, if we had one user
that exists and one that does not.
In the regular policy, we log this, and still let a rule be created from what
does exist, while in the SSH policy we did not.
This commit fixes it so the behaviour is the same.

On Windows, if the user clicks the Tailscale icon in the system tray,
it opens a login URL in the browser.
When the login URL is opened, `state/nonce` cookies are set for that particular URL.
If the user clicks the icon again, a new login URL is opened in the browser,
and new cookies are set.
If the user proceeds with auth in the first tab,
the redirect results in a "state did not match" error.
This patch ensures that each opened login URL sets an individual cookie
that remains valid on the `/oidc/callback` page.
`TestOIDCMultipleOpenedLoginUrls` illustrates and tests this behavior.
When we fixed the issue of node visibility of nodes
that only had access to eachother because of a subnet
route, we gave all nodes access to all exit routes by
accident.
This commit splits exit nodes and subnet routes in the
access.
If a matcher indicates that the node should have access to
any part of the subnet routes, we do not remove it from the
node list.
If a matcher destination is equal to the internet, and the
target node is an exit node, we also do not remove the access.

There are situations where the subnet routes and exit nodes
must be treated differently. This splits it so SubnetRoutes
only returns routes that are not exit routes.
It adds `IsExitRoutes` and `AllApprovedRoutes` for convenience.

Correctly identify Viper's ConfigFileNotFoundError in LoadConfig to log a warning and use defaults, unifying behavior with empty config files. Fixes fatal error when no config file is present for CLI commands relying on environment variables.
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.
- tailscale client gets a new AuthUrl and sets entry in the regcache
- regcache entry expires
- client doesn't know about that
- client always polls followup request а gets error
When user clicks "Login" in the app (after cache expiry), they visit
invalid URL and get "node not found in registration cache". Some clients
on Windows for e.g. can't get a new AuthUrl without restart the app.
To fix that we can issue a new reg id and return user a new valid
AuthUrl.
RegisterNode is refactored to be created with NewRegisterNode() to
autocreate channel and other stuff.
