Add Flask web UI, Docker Compose, core engine + tests

- physcom core: CLI, 5-pass pipeline, SQLite repo, 37 tests
- physcom_web: Flask app with HTMX for entity/domain/pipeline/results CRUD
- Docker Compose: web + cli services sharing a named volume for the DB
- Clean up local settings to use wildcard permissions
