Add fonts to Docker node alpine container

[ClaireWhere]

Problem

The node alpine image does not come with fonts preinstalled so the client/db/queries/insertAttachment.js module will output an image of text with no font (a bunch of boxes)

Fix

Distribute open source fonts in the image and add them to the container using something like

RUN mkdir -p /usr/share/fonts/
COPY ./fonts/ /usr/share/fonts/
RUN install -m644 /usr/share/fonts/* /usr/share/fonts/
RUN fc-cache -f -v

in client/Dockerfile
