- Partial settings are loaded before logging in via the `_ALL_IF_AUTHED` flag
- Any other attempt to findAll without flag will result in list marked as `haveAll` with the partial set of results
- Any attempt afterwards to findAll would just return the partial list and not refetch
- There were a couple of places this happened pre-log in, resulting in partial list of settings after log in
- This was needed to show version info (and to populate settings page)
- /v3 doesn't exist if multi-cluster-management is disabled
- Use /v1/management.cattle.io.settings everywhere instead of /v3
- It now returns the public set of settings if retrieve with no auth, so
the store needs to remember that even though we loaded "all" of them
that wasn't really ALL of them so that the full list gets loaded after
auth.
- Use new x-api-cattle-auth header to determine authentication state if present
- Use SETTINGS.* constants consistently
- `brand` -> `ui-brand` for consistency
- `eula-accepted=true` -> `eula-agreed=<timestamp>` to match Ember
