feat: Make component list in Nation Note more user friendly

[robertdown]

Make the list of components to insert more manageable by not rendering the body of the component, instead render the short form.

This turned out to be bigger than I had thought.

1. Adding new components or updating components now take place in a dialog
2. You can now supply a short name to the component, which will render in the list
3. Insert / Update / Delete is a bit more separated from the UI
4. Several jQuery ajax calls have been replaced with fetch() calls.
5. In the event there is only 1 category in the given context, it will automatically load that categories components.
6. The short name was expanded in the DB to allow longer names
7. The actual component is now LONGTEXT instead of TEXT in the database
8. It appears that the short title isn't used in the current structure. Since the UI list is now based on that column, the upgrade script now takes the first 35 characters of the main component text, trims it, appends an ellipsis and uses that as the short title. This prevents disruption to already existing forms

Still Pending

• SQL to copy current components into the short name and truncate (otherwise the list will break for old components)
