gh-1371 - Add readtoken when in readonly mode

[sbishel]

Summary

This PR fixes two issues.

1. When we change views on shared boards, non validated users receive an Access Denied error.
   This appears to work in Personal Server, however, because the token is not included in the query string, a refresh in Personal Server results in the same error.

Add the ?r=readtoken parameter to the url path when either displaying a different view or a card view.

2. While testing, the card view was not being displayed in read-only view.
   I think this is due to the recent route changes.

Add the /cardId? parameter to the "shared" routes.
