Fix tests and add json_store test coverage

- Fix test_ingestion.py: SCSS token names, empty CSS handling, JSON error type
- Fix test_dss_mcp_commands.py: Use relative path, update tool count to 48
- Add test_json_store.py: 22 tests covering cache, projects, tokens, components,
  activity log, teams, sync history, and stats
- Add venv/ to .gitignore

All 215 tests passing.
