fix: replace broken symlink with REPORTS_DIR env var

The ln -sf /data/reports /app/reports was creating the symlink INSIDE
/app/reports/ (since that dir already existed from COPY) instead of
replacing it. Result: sitespeed.io wrote to /app/reports/<id> and the
parser looked there too, but the volume was at /data/reports.

Fix: set REPORTS_DIR=/data/reports in Docker ENV and use it in both
runner.js (outputFolder) and app.js (static serving). No symlink needed.
Also add .dockerignore to exclude reports/, node_modules/, .git/.
