fix: finalize reviewed drawing and interaction paths

Reset stale geometry when automation replaces a drawing and resolve material paths from its directory. Cover precise indexed snapping, large-coordinate line intersections, leader ordering, invalid image buffers and browser clipboard fallback. Preserve Options dialog resizing.

Validation: cargo test --workspace --all-features (866 passed); wasm32 application check; Node clipboard regression check; Python binding tests (3 passed).
