What does this PR aim to accomplish?:

Include the raw messages from the Pi-hole diagnosis systems in debug logs

Example from an incorrect regex on the web interface:

and now in the debugger:

The interpretation of the five blob columns varies between message types. We do not do pretty formatting in the debugger to avoid having to change it for each new type of message we add (we currently have to do this already for the dashboard formatting). The mere existence of lines in here gives a hint that something is odd.

How does this PR accomplish the above?:

Add appropriate sqlite3 command to the debugger

What documentation changes (if any) are needed to support this PR?:

None
