…ent discard (#1865)

Bump the MCP SDK from 2.0.0 to 2.1.0.

SDK 2.1 sends a server/discover probe before the initialize handshake. The probe
reads a 400 response as an unsupported-protocol signal and falls back to the
initialize handshake. During interactive OAuth, that fallback calls the one-shot
authorization callback a second time. The second call fails as "authorization
already in progress" and hides the token endpoint invalid_client rejection. The
manager then keeps a dead dynamic client registration instead of discarding it.

Add OAuthClientRejectionHandler to the shared MCP HTTP pipeline. The handler
reads the invalid_client error for the authorization_code grant and throws
McpOAuthClientRejectedException before the SDK sees the 400. The SDK fallback
does not catch that type, so the true cause reaches the manager and the dead
identity is discarded. A refresh failure keeps the SDK graceful null path.

This supersedes Dependabot PRs #1777 and #1778.

Looks like ModelContextProtocol.AspNetCore is no longer updatable, so this is no longer needed.
