Removes the unreliable viewport-centre cursor heuristic. Switching to edit mode now always positions the cursor at text.length and scrolls to the bottom, whether arriving from a regular tap or a long-press. The long-press scroll-to-end on initial load (view mode) is unchanged. Cleans up _cursorAtEnd flag, _editorKey / GlobalKey, _getOffsetAtViewportCenter, and the public WrappedCodeFieldState / findRenderEditable that were only needed for the removed feature.
