Add custom tooltip

[timrid]

There are two main problems with the default windows tooltip:

• It disappears automatically after a while. So long texts are not easily readable
• it is not possible to select and copy the text from the Toolbox

To fix this a custom toolbox was created.

Pull request overview

This PR replaces the native Windows tooltip behavior in the wx-based Construct Editor with a custom, persistent popup tooltip that supports long text and text selection/copying, and adds wx integration tests around the new hover/positioning behavior.

Changes:

• Introduces WxHoverToolTip / WxHoverToolTipPopup (custom popup tooltip with wrapping, clamping, and hover/poll lifecycle).
• Wires the Construct Editor’s DVC hover logic to the new tooltip and hides it on scroll/selection/reload.
• Adds wx integration tests for tooltip timing, persistence, clamping, and Construct Editor anchoring/positioning; extends wx test harness with wait_ms() and linear mouse movement.

construct_editor/wx_widgets/wx_construct_editor.py:571

• When hovering a non-tooltip column, _on_dvc_motion returns without clearing the previous tooltip state. This can leave an unrelated tooltip visible until the poll timer hides it. Explicitly hiding here avoids showing stale tooltip content while moving across columns.

        else:
            return

construct_editor/wx_widgets/wx_construct_editor.py:574

• If the resolved tooltip text is empty, _on_dvc_motion returns without hiding the existing tooltip. That can leave the last non-empty tooltip visible even though the current cell has no tooltip content. Hiding here prevents stale tooltips.

        if not text:
            return
