Config sheds its 14 Bucket-B fields (retention, whisper, ollama, llm) and gains a sibling Arc<Settings> in AppState, loaded from settings.toml at startup via Settings::load_or_default. Workers (transcribe, analyze, recovery, auto_trigger) and routes (health, bulk, case_actions, user_web) take settings as a separate parameter or State<> extractor; Config::llm_configured moves to Settings::llm_configured. TestConfig::build_pair() returns (Arc<Config>, Arc<Settings>); the new create_router_with_settings / create_router_and_session_store_with_settings helpers wire both into integration tests that exercise LLM/Whisper/Ollama. The legacy single-Arc create_router falls back to Settings::default() so the 17 non-LLM tests stay untouched. Verified: cargo build clean, clippy --all-targets clean, 318 tests pass.
