feat(phase1): add image storage utilities

- Create backend/services/image_storage.py with 4 core functions: - sanitize_filename(): remove unsafe chars, limit to 255 chars, convert to lowercase - get_unique_filename(): handle collisions with UUID suffix (format: {name}_{uuid8}_{variant}.jpg) - ensure_image_directories(): create /images/ root and category subdirs on startup - save_image(): save bytes to /images/{category}/{filename}, returns relative path - Create comprehensive test suite (22 tests) covering all functionality - Integrate ensure_image_directories() into FastAPI startup event - Directory structure: /images/{category}/{filename} - Collision handling: auto-suffix with UUID if filename exists - All tests passing, pathlib.Path for safe operations
