Owner

Blender-style numpad view controls for the orthographic camera (#1206). We have numpad 5 = toggle orthographic / perspective; add the rest of Blender's numpad camera set:

Key	View
Numpad 1	Front
Ctrl+Numpad 1	Back
Numpad 3	Right
Ctrl+Numpad 3	Left
Numpad 7	Top
Ctrl+Numpad 7	Bottom
Numpad 2 / 8	Orbit down / up by a step (15 deg)
Numpad 4 / 6	Orbit left / right by a step
Numpad 9	Flip to the opposite view
Numpad .	Frame the selected object (centre the camera on it, Blender "View Selected")
Numpad 0	Back to the avatar camera

Behaviour

Pivot. Views snap around the current camera focus: the selected object in Build mode, else the avatar or the alt-cam focus point. They keep the current distance and orthographic zoom.
Axis views. Front, Right and Top are world axes, which suits builders lining up prims. Consider an option for avatar-relative axes.
Automatic orthographic. Snapping to an axis view switches to orthographic automatically, like Blender's auto-perspective. Orbiting away returns to perspective; the existing FSAutoPerspectiveOnCameraMove logic already does this.
Smooth. Animate the snap over about 150 ms (camera smoothing), with no hard cut. The temporal history is reset on the cut, as the ortho toggle already does.

Input

NumLock. Same issue as #1222. These must work regardless of NumLock without breaking typed digits and gesture keys:
- only take the keypad while the camera is under user control (alt-cam / build / flycam focus), or
- use NumLock-off bindings plus modifier alternatives.
Decide this together with #1222.
Rebindable. All bindings appear in Preferences > Controls (key binding table rows). Bump the key bindings xml_version so saved files get the defaults (see the v2 migration in LLViewerInput::loadBindingsXML).
Discoverable. The camera floater gets a small view picker (Front / Right / Top / ...) for mouse users.

Not in VR

Refuse in a VR session, as ortho already does.
