Updates #5435
Based on the discussion in #5435, we can better support transactional data models
by making the underlying storage layer a parameter (which can be specialized for
the request) rather than a long-lived member of Authority.
Now that Authority is just an instantaneous snapshot of state, we can do things
like provide idempotent methods and make it cloneable, too.

The CapabilityFileSharingTarget capability added by eb32847d85
is meant to control the ability to share with nodes not owned by the
current user, not to restrict all sharing (the coordination server is
not currently populating the capability at all)

Needed to identify the node. A serverside-check the machine key (used
to authenticate the noise session) is that of the specified NodeID
ensures the authenticity of the request.

Hashing []any is slow since hashing of interfaces is slow.
Hashing of interfaces is slow since we pessimistically assume
that cycles can occur through them and start cycle tracking.
Drop the variadic signature of Update and fix callers to pass in
an anonymous struct so that we are hashing concrete types
near the root of the value tree.

- A network-lock key is generated if it doesn't already exist, and stored in the StateStore. The public component is communicated to control during registration.
- If TKA state exists on the filesystem, a tailnet key authority is initialized (but nothing is done with it for now).

This adds the inverse to CapabilityFileSharingSend so that senders can
identify who they can Taildrop to.
