fix: keep requested MCP OAuth scope when DCR response omits it (#30384)
MCP tool servers using OAuth 2.1 with dynamic client registration authorized without any scope when the authorization server left scope out of its registration response, which RFC 7591 allows (Atlassian and Notion do). Consent completed and the tool showed as connected, but the issued token lacked the scopes the resource requires, so every tool call was refused. Discovered scopes and the custom OAuth Scopes field were both affected.

The stored client now falls back to the scope sent in the registration request when the response has none. A scope the server does return is kept as is.

Connections registered before this fix already have a null scope stored. The protected resource metadata recovery that static-credential clients already use now also runs for dynamically registered clients, so those connections pick up the discovered scopes on the next load without registering again.

Fixes #29967
