sndev cleanup

[huumn]

closes #1533

You'll have to delete and restart containers after this is merged. It renames stacker_(lnd|cln) to (lnd|cln) and relies on docker compose labels to provide access to service clis/onions/certs now.

This replaces:

• sndev fund_user -> sndev set_balance
• sndev (stacker|sn)_(lndcli|clncli|litcli) -> sndev cli (lnd|sn_lnd|cln|litd)
• sndev (stacker_(lnd|cln)|lnbits) get_onion -> sndev onion (lnd|cln|lnbits)
• sndev stacker_lnd get_cert -> sndev cert lnd
• sndev (fund|withdraw)_cln -> sndev (fund|withdraw) --cln

This adds:

• sndev test command (which just runs our one jest test)

This is unrelated to the pr, but i've noticed that some sndev commands do not work in my ubuntu workstation if i run it with ./sndev. The cause seems to be the use of bash conditional expressions [[ ]] that are not supported by the real /bin/sh (even though /bin/sh might be a symlink to /bin/bash in some distro).

Imo for correctness we should use the shebang #!/bin/bash , if it doesn't cause issues in other OSes

[huumn]

That's weird because it passed the shellcheck check job we run on prs.

[huumn]

Ah it's not catching that problem because it's just a warning. I'll fix that in this pr. I think I added a few more of those bash syntax conditionals.

[huumn]

Should be fixed. There was just one usage of [[ COND ]] in fund_user (now set_balance).
