fix: resource path cleanup + mount processing_routes WIP

- config.rs: SCRIPTS_DIR fix, EMBED/OLLAMA_URL 127.0.0.1, PYTHON_PATH restored
- executor.rs: use config::PYTHON_PATH instead of hardcoded path
- probe.rs/watcher.rs: use config::SCRIPTS_DIR instead of hardcoded path
- release.rs: momentry_core_0.1 → momentry_core
- .env.development: fix REDIS_URL host, PYTHON_PATH, SCRIPTS_DIR
- api/mod.rs + server.rs: add processing module declaration (routes not yet mountable due to pre-existing compile errors)
