cmd/tailscale/cli: stabilise the output of `tailscale lock status --json`
This patch stabilises the JSON output, and improves it in the following
ways:
* The AUM hash in Head uses the base32-encoded form of an AUM hash,
consistent with how it's presented elsewhere
* TrustedKeys are the same format as the keys as `tailnet lock log --json`
* SigKind, Pubkey and KeyID are all presented consistently with other
JSON output in NodeKeySignature
* FilteredPeers don't have a NodeKeySignature, because it will always
be empty
For reference, here's the JSON output from the CLI prior to this change:
