Use add_borders.py for real SVG hand-drawn photo borders

- ImageService now calls the website repo's add_borders.py via subprocess
  instead of drawing simple wobble rectangles. Fails if not configured.
- Added WEBSITE_REPO_PATH env var to config (documented in .env.example)
- Added find_existing_photo() to check images/people/ for pre-placed photos
- Added is_photo_bordered() to detect already-processed photos
- Passed website_repo_path to ImageService in onboard handler
