Log verbose progress messages in S/R at debug level

[rmunn]

Fix #1162.

The stripping out of passwords might be redundant because Chorus is supposed to already do this, but I've seen a few cases of passwords in logs recently, apparently due to a Chorus bug that's not yet completely squashed. Once we're confident that Chorus is no longer logging passwords we can remove the extra sanitization step, but for now let's keep it to be safe.

Tested locally and it works: change LogLevel.Default in backend/FwHeadless/appsettings.Development.json from "Information" to "Debug" and you'll start seeing debug logs showing every step of the Send/Receive process when you do a CRDT sync with FwHeadless.

looks good to me, in the future we might want to take advantage of log scopes so that each message is annotated with the project it's in reference too, otherwise if 2 syncs are going at once we won't be able to track what's going on.
