Uploading/deleting Event Templates produces no Notifications

[andrewazores]

POST /api/v1/templates and DELETE /api/v1/templates/:templateName endpoints both produce a WebSocket notification on success (as well as indicating success by the HTTP status code in the response). However, neither of these produce a graphical notification in the web-client.

At face value this comes down to the NotificationChannel.service.tsx simply not subscribing to the stream of messages with this category. However, this would be a recurring problem with more event categories that are added - and may already be an issue with other categories than the two for Event Templates. There is already some logic in the Notifications.tsx for determining whether a WebSocket message indicates some kind of "action" event (response to a user-initiated or automated API request), a "problem" (some API request failed), reflects WebSocket client activity, or indicates that a target JVM (dis)appeared. Rather than the NotificationsChannel.service.tsx explicitly opting in to some set of categories for which to display notifications, perhaps it should listen to all incoming messages with all categories, and display notifications for all of the ones that are "actions".
