This commit modifies the k8s operator to allow for customisation of the ingress class name
via a new `OPERATOR_INGRESS_CLASS_NAME` environment variable. For backwards compatibility,
this defaults to `tailscale`.
When using helm, a new `ingress.name` value is provided that will set this environment variable
and modify the name of the deployed `IngressClass` resource.

This commit modifies the operator helm chart values to bring the newly
added `loginServer` field to the top level. We felt as though it was a bit
confusing to be at the `operatorConfig` level as this value modifies the
behaviour or the operator, api server & all resources that the operator
manages.

With this change, policy enforcement and exit node resolution can happen in separate steps,
since enforcement no longer depends on resolving the suggested exit node. This keeps policy
enforcement synchronous (e.g., when switching profiles), while allowing exit node resolution
to be asynchronous on netmap updates, link changes, etc.
Additionally, the new preference will be used to let GUIs and CLIs switch back to "auto" mode
after a manual exit node override, which is necessary for tailscale/corp#29969.

TestSetControlClientStatusAutoExitNode is broken similarly to TestUpdateNetmapDeltaAutoExitNode
as suggestExitNode didn't previously check the online status of exit nodes, and similarly to the other test
it succeeded because the test itself is also broken.
However, it is easier to fix as it sends out a full netmap update rather than a delta peer update,
so it doesn't depend on the same refactoring as TestSetControlClientStatusAutoExitNode.

suggestExitNode never checks whether an exit node candidate is online.
It also accepts a full netmap, which doesn't include changes from delta updates.
The test can't work correctly until both issues are fixed.
Previously, it passed only because the test itself is flawed.
It doesn't succeed because the currently selected node goes offline and a new one is chosen.
Instead, it succeeds because lastSuggestedExitNode is incorrect, and suggestExitNode picks
the correct node the first time it runs, based on the DERP map and the netcheck report.
The node in exitNodeIDWant just happens to be the optimal choice.
Fixing SuggestExitNode requires refactoring its callers first, which in turn reveals the flawed test,
as suggestExitNode ends up being called slightly earlier.
In this PR, we update the test to correctly fail due to existing bugs in SuggestExitNode,
and temporarily skip it until those issues are addressed in a future commit.

Currently, (*LocalBackend).pickNewAutoExitNode() is just a wrapper around
setAutoExitNodeIDLockedOnEntry that sends a prefs-change notification at the end.
It doesn't need to do that, since setPrefsLockedOnEntry already sends the notification
(setAutoExitNodeIDLockedOnEntry calls it via editPrefsLockedOnEntry).
This PR removes the old pickNewAutoExitNode function and renames
setAutoExitNodeIDLockedOnEntry to pickNewAutoExitNode for clarity.

This value is set in the `loginServer` helm value and is propagated down to all resources

Instead of calculating the PeerAPI URL at the time that we add the peer,
we now calculate it on every access to the peer. This way, if we
initially did not have a shared address family with the peer, but
later do, this allows us to access the peer at that point. This
follows the pattern from other places where we access the peer API,
which also calculate the URL on an as-needed basis.
Additionally, we now show peers as not Available when we can't get
a peer API URL.
Lastly, this moves some of the more frequent verbose Taildrive logging
from [v1] to [v2] level.

Previously, the operator checked the ProxyGroup status fields for
information on how many of the proxies had successfully authed. Use
their state Secrets instead as a more reliable source of truth.
containerboot has written device_fqdn and device_ips keys to the
state Secret since inception, and pod_uid since 1.78.0, so there's
no need to use the API for that data. Read it from the state Secret
for consistency. However, to ensure we don't read data from a
previous run of containerboot, make sure we reset containerboot's
state keys on startup.
One other knock-on effect of that is ProxyGroups can briefly be
marked not Ready while a Pod is restarting. Introduce a new
ProxyGroupAvailable condition to more accurately reflect
when downstream controllers can implement flows that rely on a
ProxyGroup having at least 1 proxy Pod running.

Relay handshakes may now occur multiple times over the lifetime of a
relay server endpoint. Handshake messages now include a handshake
generation, which is client specified, as a means to trigger safe
challenge reset server-side.
Relay servers continue to enforce challenge values as single use. They
will only send a given value once, in reply to the first arriving bind
message for a handshake generation.
VNI has been added to the handshake messages, and we expect the outer
Geneve header value to match the sealed value upon reception.
Remote peer disco pub key is now also included in handshake messages,
and it must match the receiver's expectation for the remote,
participating party.
