Prevent viewer role users from getting 404 when accesing applications

[cstns]

Description

• removed the 403 triggering api calls from the application page/mixin (alongside the devices api call) and stopped passing the devices & deviceGroups as props to the router in order to leave the components that actually need that data to get it themselves
• hid and added 'route guards' to the device groups, application pipelines, and audit log tabs
• altered the navigation routes to use named routes instead of hardcoded ones
• prevented the audit log, device groups and pipelines pages from calling api endpoints when the user accessing them doesn't have sufficient premissions
• had to load deviceGroups and devices on the pipelines page after removing them from their parent
