Improve: three-state online host list sorting

Browse Source 
Clicking the same column header now cycles ascending -> descending ->
restore default order instead of only toggling direction. The default order
is the host connection order, reconstructed by sorting on online time
(descending alive time) so it no longer depends on the in-memory append
order surviving an earlier sort. The reset preference is persisted as an
empty value so it survives a restart.
