* Add type schema for enum values
* Refactor: closed values instead of enum to limit values
There's no need to add the enum type, we just want to limit the
values.
* feat: :page type supports closed values
* fix: can't set property values for text/number types
* fix: don't trigger on-chosen when unmounting any select component
* fix: can't apply both page classes limitation and closed values
* fix: merge conflicts
* fix: ui not refresh when changing closed value
* fix: can't set icon for closed value
When 2 db graphs exist, the built-in-properties check failed because it
failed to db lookup for the new repo. Just simplified it so that db
lookup is only needed once across repos. Also limited check to hidden
built-in properties since visible built-in properties should be
treated like user properties and be collapsable
Also fixed structured tag popup displaying
in heading which didn't make sense. Since this was fixed
right after gp-block/extract-blocks is called, this likely
fixed related issues where format/extract-blocks is called e.g. paste.
Fixes LOG-2821.
All of frontend.util.page-property was file based except for one line.
Moved that ns to a file-based ns and moved the line out to the more
appropriate property-handler
db-graph related fns like these shouldn't be in the graph-parser dep as
that dep should only really be used with file graphs as much as possible.
This is also being done in preparation for making the create-graph ns independent of
the frontend
Also db- prefixes in fns were dropped since the ns now carries the db-
prefix
