Root cause: WhiteboardApp.zoomReset() in app.js sets stage.scale(...) and stage.position(...) directly without calling WhiteboardCanvas.saveView(). The same issue exists in fitMindmapToView() (used by the mindmap fullscreen view).

Fix: call WhiteboardCanvas.saveView() at the end of both functions, and before each early-return that has already mutated the stage.

Clicking the Fit button in the zoom toolbar re-centers and rescales the stage to fit all content, but the resulting zoom/pan is not written to localStorage. After a page reload the board comes back at its previously-saved view (from the last wheel/drag/setZoom) instead of the fitted view. Root cause: `WhiteboardApp.zoomReset()` in `app.js` sets `stage.scale(...)` and `stage.position(...)` directly without calling `WhiteboardCanvas.saveView()`. The same issue exists in `fitMindmapToView()` (used by the mindmap fullscreen view). Fix: call `WhiteboardCanvas.saveView()` at the end of both functions, and before each early-return that has already mutated the stage.
