some changes and improvements alongside bugfixes

[DaveDarsa]

This PR does the following:

• fixes numeric sort in a couple places using <PaginatedTable/>
• adds "sort-by-role" functionality on the users page
• changes deletion modal texts to be accurate
• modals understand where the user is being updated or added
• users table has a "show/hide default users" filter
• each table now shows their row at their headers
• Adds project links to organization projects
• adds loading/disabled indicator to action buttons to avoid repeated mutations
• fixes group -> user link
• and some smaller issues

[DaveDarsa]

@tobybellwood the issue with number of users shown on the Users page and the Group page is there because usersByOrganization and groupByNameAndOrganization queries return users that are different.

Technically these aren't project routes - maybe ProjectDashboard would be better - and maybe opening in a new tab by default?

Suggested change

	<ProjectRoute>ROUTE</ProjectRoute>
	<ProjectRoute>View in Dashboard</ProjectRoute>

[DaveDarsa]

• <ProjectDashboard/> opens a new tab to project dashboard
• Table counters fixed ( shows all item count, or searchString-filtered item count)
• Default user / System group tags added where missing previously

ooh - looking good now!
