0cc7e51da2 Drags: added value ladder: stepped value editing with explicit magnitude selection (Houdini-style) (#9463) 
Hold middle mouse button over a DragXXX widget to open a vertical ladder
of step magnitudes: drag vertically to select the step magnitude,
horizontally to add/subtract steps of that size. Release middle mouse
button to confirm, press Escape to cancel and revert to the initial value.

- Enable globally with io.ConfigDragValueLadder or per-widget with
  ImGuiSliderFlags_ValueLadder.
- Rungs are powers of ten, from the smallest step representable with the
  display format (1 for integers) up to 10000. For bounded widgets, rungs
  covering the whole range or more are dropped.
- Keyboard/gamepad navigation support: activating the widget
  (Space) opens the ladder, Up/Down select the step magnitude,
  Left/Right add/subtract steps, Space confirms, Escape cancels and
  reverts.
- The ladder is disabled when it would yield fewer than 3 rungs.
- Unlike regular drag speed tweaks (Alt/Shift), the ladder makes the
  current step magnitude visible and exact, and any size of change is
  reachable without a range.
- Min/max clamping, wrap-around and display format rounding behave the
  same as regular mouse drags (reuses the DragBehaviorT pipeline).
- Multi-component widgets (DragFloat3 etc.) get a ladder per component.
- Overlay is drawn on the viewport foreground draw list, so it cannot
  interfere with inputs and may spill outside the host window.
  The overlay grows (monotonically, staying centered and clamped into
  the viewport) whenever the formatted value is wider than the box.
- Not supported together with ImGuiSliderFlags_Logarithmic.
- Demo: added dedicated Widgets->Value Ladder section, checkboxes in
  Configuration->Widgets and Widgets->Drag/Slider Flags.
- Added DataTypeAsDouble() to the DataTypeXXX API (replacing the local
  ValueLadderGetValueAsDouble() helper). Range span is computed with
  DataTypeApplyOp() subtraction followed by DataTypeAsDouble(), which
  also clamps integer overflow.

Addresses feature request #9463.
