feat: Add uc wg show command to inspect a machine's uncloud wireguard network (#161)

* feat: Add `uc wg show` command to inspect a machine's uncloud wireguard network (draft / work in progress)

* Compile proto files with `make proto-mise`

* Fix lint errors

* Output peers in tabwriter table

* Lookup machine name for wireguard peer public key

* Add --machine flag to `uc wg show` to proxy call to specific machine

* Small refactor to move wg show logic out into a separate function
