(*LocalBackend).setControlClientLocked() is called to both set and reset b.cc.
We shouldn't attempt to start the audit logger when b.cc is being reset (i.e., cc is nil).
However, it's fine to start the audit logger if b.cc implements auditlog.Transport, even if it's not a controlclient.Auto but a mock control client.
In this PR, we fix both issues and add an assertion that controlclient.Auto is an auditlog.Transport. This ensures a compile-time failure if controlclient.Auto ever stops being a valid transport due to future interface or implementation changes.

Resetting LocalBackend's netmap without also unconfiguring wgengine to reset routes, DNS, and the killswitch
firewall rules may cause connectivity issues until a new netmap is received.
In some cases, such as when bootstrap DNS servers are inaccessible due to network restrictions or other reasons,
or if the control plane is experiencing issues, this can result in a complete loss of connectivity until the user disconnects
and reconnects to Tailscale.
As LocalBackend handles state resets in (*LocalBackend).resetForProfileChangeLockedOnEntry(), and this includes
resetting the netmap, resetting the current netmap in (*LocalBackend).Start() is not necessary.
Moreover, it's harmful if (*LocalBackend).Start() is called more than once for the same profile.
In this PR, we update resetForProfileChangeLockedOnEntry() to reset the packet filter and remove
the redundant resetting of the netmap and packet filter from Start(). We also update the state machine
tests and revise comments that became inaccurate due to previous test updates.

There was a flaky failure case where renaming a TLS hostname for an
ingress might leave the old hostname dangling in tailscaled config. This
happened when the proxygroup reconciler loop had an outdated resource
version of the config Secret in its cache after the
ingress-pg-reconciler loop had very recently written it to delete the
old hostname. As the proxygroup reconciler then did a patch, there was
no conflict and it reinstated the old hostname.
This commit updates the patch to an update operation so that if the
resource version is out of date it will fail with an optimistic lock
error. It also checks for equality to reduce the likelihood that we make
the update API call in the first place, because most of the time the
proxygroup reconciler is not even making an update to the Secret in the
case that the hostname has changed.

updates tailscale/corp#27145
We require a means to trigger a recompilation of the DNS configuration
to pick up new nameservers for platforms where we blend the interface
nameservers from the OS into our DNS config.
Notably, on Darwin, the only API we have at our disposal will, in rare instances,
return a transient error when querying the interface nameservers on a link change if
they have not been set when we get the AF_ROUTE messages for the link
update.
There's a corresponding change in corp for Darwin clients, to track
the interface namservers during NEPathMonitor events, and call this
when the nameservers change.
This will also fix the slightly more obscure bug of changing nameservers
while tailscaled is running. That change can now be reflected in
magicDNS without having to stop the client.

1) when store is initialized, lookup additional

from there
2) if the node runs in certs 'read only' mode and
TLS cert and key are not found in the in-memory store,
look those up in a Secret
3) if the node runs in certs 'read only' mode, run
a daily TLS certs reload to memory to get any
