"mc-agent cli -c list" should not return exit code 0 on error

Currently mc-agent cli -c list always returns exit code 0, even there is some error, so Mooltipass GUI, SSH Keys tab can't distinct empty list of keys from any error occured.

Actual result:

$ mc-agent cli -c list
[]
$ echo $?
0

Now exit code is always 0 no matter what:

• Mooltipass device is not connected
• Security card is not inserted
• Mooltipass is locked
• Getting "moolticute ssh keys" wasn't confirmed

Expected result:

Exit code should be non-zero in a case of any error.
Moolticute GUI, "SSH Keys" tab should show an error if SSH Keys was not loaded from a device.

Only absence of "moolticute ssh keys" file is a normal situation and exit code should be 0
if there is no such file on a Mooltipass device (mc-agent wasn't used yet).

I did some testing (with a Mini BLE), and apparently only the last case Getting "moolticute ssh keys" wasn't confirmed is indistinguishable from the missing file.

The other cases send a mp_disconnected or status_changed message and could be better handled to return some other exit code (I have a prototype here: https://git.sr.ht/~oliverpool/go-moolticute/tree/main/item/client.go)
