This change updates the Automation plugin to make use of the `use_new_show_route` plugin flag, as well as generally updating the UI to match current admin UI guidelines. Notable changes include:
- Moving template/router/controller files to make use of the `admin.adminPlugins.show` route.
- Changing the URIs from `/admin/plugins/discourse-automation` to `/admin/plugins/automation`, to match the `PLUGIN_NAME`.
- Adding UI wrappers around the New/Edit forms, and polishing the list of defined automations.
A `UserHistory` entry will now be created when an automation is destroyed. This is visible in `/admin/logs/staff_action_logs`. id, name, trigger and script will be logged.
This commit also creates a service `DestroyAutomation` to hold all the destroy automation logic.
