Make SmartEvidence keyboard accessible

[Kristina Hoeppner]

1. Screen reader detects a table with 1 row and 1 column - this prevents user from navigating properly through the table cells
2. There are clickable elements which don't seem to have text equivalents
3. The interactive elements inside the SmartEvidence table are not keyboard accessible. Keyboard users should be able to tab to the elements and activate them with Space or Enter

For more information on how best to resolve these, please have a chat with Julius, Cecilia.

Bug 1701083: SE matrix accessibility

- Modified tags in template so screen readers
can see them correctly
- Tabbing goes through each cell of the table
and collapsible sections heading
- Opening a modal sets focus on the delete button
of the modal ('X')
- Tabbing inside a modal dialog loops through the
elements of that dialog
- Closing modal dialog sets focus back on the
annotation cell
- Clicking on standard title (first cell of a row)
will display description of standard. The element
can also be reached with tab key and description
can be opened with enter key. The description box
disappears when it loses focus
