Fix CI: copy repo into custom_components instead of symlink (#52)

The symlink caused pytest to collect __init__.py from both the repo root
and the symlinked path, triggering relative import errors. Copying the
repo into /tmp/ha-config/custom_components/solar_energy_management/ and
running pytest from there ensures __init__.py is properly inside its
package hierarchy.
