Fix path resolution and sync canonical test.raw.json for submission validation

- Use __file__-relative paths in schema.py and app.py so validation works
regardless of working directory (fixes test imports and Space deployment)
- Sync leaderboard_space/data/test.raw.json with canonical stwebagentbench/test.raw.json
to fix policy template_id mismatches during submission validation
