fix: open DuckDB read_only in trajectory helpers to avoid lock conflict with Streamlit

Browse Source 
Both _load_window_ids and _load_mp_vectors_for_window only read from the DB.
Opening without read_only=True caused an IOException when Streamlit already held
a read-only lock, silently returning an empty scree plot.
