What does this PR do? What is the motivation?

The Okta steps on the Cross-App Access page use labels from an older Okta Admin Console. This PR updates them to match Okta's current Cross App Access docs:

• Resource app: Machine Assignments > Callers > Cross App Access (XAA) replaces the "Resource Server" tab. The OIN app sets Issuer URL and Scopes; the admin enters the org UUID as Audience/tenant ID.
• AI agent: Directory > AI Agents > Register AI Agent, with the Claude app linked under Allow users to access this agent (replaces the Delegations tab), the public key on the Client registration tab (replaces Credentials), and users assigned on the User access tab.
• Resource connection: the resource URL moves here as Resource indicator. "Client ID at resource" becomes AI agent's client ID registered in this app, and "Scope Condition: Allow all" becomes Scopes: Allow any scope.
• Prerequisites: replaces the two feature-flag names with Okta's SSO requirement and its 250 ID-JAG tokens per user, per resource app, per month limit.
• Issuer: notes that the issuer must be the Okta org URL, not a custom authorization server or a custom URL domain.

Okta sources: overview, resource app, AI agent, connection, token exchange.

Needs a check in a live Okta org before merge. The labels come from Okta's public docs, not the console. Please confirm:

• the Datadog OIN app pre-fills Issuer URL and Scopes
• the agent's Client ID is what Anthropic needs (the old text said "AI Agent ID")
• an owner is still required before activation (kept from the old text; Okta's page doesn't mention it)
• the public/private key method is the right one for Claude

This touches the same file as #41188 but stays out of the issuer-rules lines it edits.
