config: add config package and wire it into server and handlers

Replace the hardcoded server.Config with an ini-backed config package
that reads /etc/openstore/openstore.conf then the user's config file, so
user settings override system ones and both override the built-in
defaults. Missing files are ignored rather than fatal.

Move route registration into a handlers package that owns the templates
and builds a Page view model, which removes the server -> handlers
import cycle along with the setter-based context injection.
