Add View pages for admin resources

[Boy132]

In order for the view permissions to actually do something we need to add view pages (ViewRecord) to the following resources:

• [ ] Egg
• [ ] Node
• [x] Role
• [ ] Server
• [x] User
• [x] API Key (?)
• [x] Database Host
• [x] Mount
• [x] Webhooks

We either take the existing forms and just make them read-only when viewing (which Filament does by default) or create separate infolists.
