refactor: Split ES2 client into separate files for better code organization

- Move ES2 request/response types to es2_types.go
- Move profile operations (download, activate, deactivate, delete, status, list) to es2_operations.go
- Move helper methods (send requests, validation, generateRequestID) to es2_helpers.go
- Keep core ES2Service struct and ProvisionProfile in es2_client.go
- Revert sendDeactivationRequest parameter type from any back to interface{}
