amari/*: fix password connection

Hello @kirr , in a recent commit of simpleran software release I added a
password to the lteenb websocket: nexedi/slapos@77c00979

Since then the xlog service has stopped working correctly with the following error:

    {"meta": {"event": "service detach", "time": 1734710968.4153636, "srv_name": "ENB", "srv_type": "ENB", "srv_version": "2024-11-21", "reason": "handshake: service requires authentication, but no password provided"}}

After a bit of debugging I found out that there are several calls to
amari.connect but the password is given in parameter in only one of those call,
which explains the error above.

I included the password in all "amari.connect" calls and it looks like xlog is
working correctly with this commit.

I am not sure if this commit breaks anything or if this is the right way to do
it as I didn't spend too much time checking the code, when you have time could
you please review ?

Thank you,
Joanne
