Draft: Some accessibility improvements

• article instead of div for statuses
• various text labels for actions
• some aria-expanded

Something that needs to be resolved:

• there are instances of "nested" pushbuttons on popovers ("add reaction pushbutton collapsed" TAB "pushbutton")
• "Expand" and "Collapse" (in the timeline) should ideally be the same button
• Timelines should be lists of articles

Closing this as it overlaps with !1679 (merged) . Other things are to be handled separately.
