Keypad bindings, add rotate and change location of zoom

Expected behavior of the wanted feature

Since recently the keypad got utilized more, but also broke some behavior. As I explored the new keybindings on the keypad, they seem somewhat unnatural to me.
The video scale is fine with: down KP2, up KP8, left KP4 and right KP6.

Though the zoom-in on KP9 and zoom-out on KP1, diagonally opposite to each other seam somewhat unhandy. There was also a discussion to add rotate to the keybindings, but these don't seem to work for me.

My proposal would be to

set zoom on KP7 and KP9

set rotate on KP1 and KP3, preferably with 45° (or 22.5°) angles left and right

as KP3 and KP7 are unbound at the moment.

KP0 is also unbound and could be used as a reset and KP. could be used as an 'unreset/undo recent reset'.

Start by reviewing mpv's existing keypad bindings and the behavior discussed in issues #15416 and #5458. Compare the proposed zoom, rotate, reset, and undo mappings with the currently unbound keys, then verify that the agreed bindings and rotation behavior work consistently.
