Implement change propagation suitable for phase 2. Specifically:

• client pages need to be re-rendered when entity claims change
• client pages should not be re-rendered (but squids need to be purged) when site links change (see also 45534)
• modifications of labels, aliases and descriptions can be ignored by the client.
