obs-outputs: Change loglevel of ftl status thread to debug

The ftl output gets very spammy (3-6 lines every 5 seconds),
this commit changes the loglevel of those messages to debug
so they do not clutter up the logs of users.

In case these messages are needed they can be re-enabled using
the '--verbose' flag.

(also fixes minor formatting issues)
