I would not have expected it to exist on your system.  It is where I
put a second copy of MythTV when I am testing new versions prior to
using them in real life.

Not present - those "files" are just links to a place where the files
are not actually present - the same links you saw before.  They should
be coloured red if you have colouring enabled, showing that they are
bad links.  My command "rm -v Droid*" in the install instructions
above should have deleted all the bad links.

If faginbagin is right, the bug report he gave us a URL for says it is
a packaging issue that has happened in v30's Ubuntu packages.  The
packages do not install the fonts.  I know from my test builds of v30
that the fonts were in v30 when I downloaded and built it from the
source code - that was how I had them in my
/root/projects/mythtv-master/mythtv/mythtv/themes/fonts/ directory.

Yes, using the MythCentre-wide theme, everything just does not feel
right until those fonts are installed.

Yes, copying the backend's config.xml and just changing the IP address
is the best way to make sure it will work.  However, it does rely on
each frontend box having a different hostname.  That is usually the
case, as the install process for every version of Linux I know of gets
you to select a hostname for the box.  But just to make sure, you can
run this command on the RPi:

hostname

to see what the hostname is set to.  If is vitally important that all
PCs on a network have different hostname settings.

When you set a <LocalHostName> value in a config.xml file, that value
gets used to look up the frontend settings in the backend's database,
instead of using the actual hostname of the PC.  That is a specialised
use of MythTV - you can make multiple different frontends use the same
settings.  But it can also cause problems.  So I am surprised that the
RPi version of MythTV seems to either set the <LocalHostName> value,
or tell you to do it.  It is usually a bad idea unless you know
exactly what you are doing.
