feat(clerk): Add CRUD endpoints to existing objects

[wobsoriano]

What kind of change does this PR introduce?

1. Adds INSERT, UPDATE, and DELETE support to Clerk FDW for supported endpoints
2. Adds single-item retrieval by ID support (ID pushdown)

What is the current behavior?

• Clerk FDW only supports SELECT. INSERT, UPDATE, and DELETE return errors or no-ops.
• Querying a specific resource by ID fetches all records and filters locally.

What is the new behavior?

• Full CRUD: users, organizations, jwt_templates, oauth_applications, saml_connections
• Insert + Delete: allowlist_identifiers, blocklist_identifiers, redirect_urls
• Insert only: invitations
• Update + Delete: domains
• ID Pushdown - users, organizations, jwt_templates, oauth_applications, saml_connections, redirect_urls

Additional context

• Follows Orb FDW patterns (structure) and Paddle FDW patterns (PATCH for updates)
• Documentation updated to reflect CRUD support and retrieve-by-ID notes
