feat(management): add agents, org clients, network ACL keys, and org role groups

[developerkunal]

🔧 Changes

Adds new endpoints and their backing types to the management API.

• Agents: new Agents client with List (cursor-paginated), Create, Read, Delete, and Update for managing agents.
• Organizations → Clients: new Organizations.Clients client with List (checkpoint-paginated), Create, Delete, Get, and Update for managing organization-client associations. Organization responses now expose is_app_entitlement_active and client.
• Organizations → Roles → Groups: new Organizations.Roles.Groups client with List to retrieve groups assigned to a role within an organization.
• Keys → Network ACLs: new Keys.NetworkACLs client with Create for keys used to verify HTTP Message Signatures on Network ACL rules.
• Connections → Directory Provisioning: adds AddSynchronizedGroupSelections and DeleteSynchronizedGroupSelections.
• Roles: role responses now expose type (RoleTypeEnum) and owner_id.

Fixes

• EventStreams.Deliveries.List now decodes the deliveries list and next cursor from the response object and returns a *core.Page[...]. Previously it decoded the response directly into a slice, which did not match the endpoint's actual payload, so the next cursor was never surfaced and pagination did not work.

🔬 Testing

Covered by new and updated unit tests across management (new agents_test, organizations_clients_test, organizations_roles_groups_test, keys_network_acls_test, plus updates to types_test.go, requests_test.go, and the directory provisioning, organizations, roles, and event-stream delivery tests) and the updated wiremock mappings. go build ./... and go vet ./management/... both pass.

📝 Checklist
