fix(terminal): refresh process info on tab bar hover/focus and fix tests

Refresh process info when the tab bar is hovered or gains focus,
and when a terminal is activated. Update integration tests to use
the exported _refreshAllProcesses instead of the removed mouseenter
trigger. Bump tab bar expand threshold to 840px. Improve tab text
visibility with larger font and better contrast.
