fix(ui): measure dead pad space from cursor instead of absolute height

Browse Source 
Remove the /autoping warning subcommand and PREF_AUTOPING_WARNING
preference entirely. The warning was shown at connect time when
autoping was disabled but the server supported XEP-0199 ping.

The pad threshold logic previously used an absolute height
(PAD_THRESHOLD=12000) which was above the buffer cap and never
fired during normal scrolling. Replace with a dead-space measurement
(cursor position minus live buffer lines) that only triggers a redraw
when dead space exceeds PAD_DEAD_SPACE_LIMIT (2000 lines).
