Timeline refinement

[kjacks]

Styling

• [x] font styling discrepancies between develop and prod
• [x] increase the font-size for prop field labels?
• [x] theme color for an event doesn't always carry through
• [x] ensure hover styling for all fields is consistent

Structure/Functionality

• [ ] Support tab navigation through the timeline item fields
• [x] All entity-type properties should appear on the left (currently "Involved" and edge props do so)
• [x] When creating a new involved (or other) entity reference, createEntityDialog should auto-populate with what you've already typed in the suggest component
• [x] For Events - "Summary" and "Description" properties are confusingly similar -> edit FTM featured props
• [x] it's a bit inconsistent which items stay active when toggling collapse/uncollapsed mode
• [x] Color picker should be visible when initially creating a timeline item (otherwise it's a pretty hidden feature)
• [x] Date sorting needs to sort by combined "date" and "startDate" properties
• [x] BUG: edge case - When creating an item, if a value is added for a caption property that is not the first in the array of caption props, and there is no value for the first caption prop, then it replaces the main caption field

Other questions

• Should end date field be visible by default?
• Should we revisit having a flexible date picker for date fields?
• Aleph doesn't really deal in times, but datetimes are technically supported in the current date field inputs - should we make this more explicit? should we disallow this?
• Should we revisit only allowing Events versus all Interval entity types
