Implement issue #10895990: Better durations for proc stats

Browse Source 
Add new option to select data duration to show, with the default
being 3 hours.

Reworked how menus are updated to remove redundant code.

Switch to using new proc stats service API for retrieving stats,
which is more efficient and won't hit IPC limits.

Fixed layout for details items to ellipsize long items.
