fix(key-bindings): make numeric keypad work in application mode

We switch the terminal into application keypad mode (smkx) so terminfo
key bindings are valid, but that also makes the numeric keypad send
escape sequences (\eOp..\eOy, \eOM, ...) that were never bound. Keypad
Enter rang the bell instead of running the command.

Map each keypad sequence back to the plain key with `bindkey -s`, so it
behaves exactly like the main keyboard key in emacs, viins and vicmd.

Fixes #13928
