This change introduces two new filters on the example clients page - allowing users to filter clients that support Dynamic Client Registration (DCR) and Client ID Metadata Documents (CIMD). I also added an MCP client that supports DCR as a part of this PR.

I'm pretty sure this is part of #1738.

Motivation and Context

Currently, there is no source of truth on the internet for which clients support DCR or CIMD. Adding these filters allows developers implementing MCP Auth to understand which clients support what client registration method, if at all.
