feat: add PayPal sandbox/live credentials, webhook endpoint, and admin diagnostics

- config.inc.php: new sandbox/live credential structure with paypal_mode, separate
  sandbox/live client_id, client_secret, webhook_id, and webhook_path
- config.example.php: updated to match new structure
- config_loader.php: adds defaults and backward compat mapping from old
  $paypal_sandbox/$paypal_client_id variables; adds gsp_paypal_* helper functions
- PayPalGateway.php: fromConfig() uses gsp_paypal_* helpers with fallback
- cart.php: uses gsp_paypal_get_client_id()/gsp_paypal_is_sandbox() helpers
- webhook.php: updated to use gsp_paypal_* helpers for credentials/API base
- paypal/webhook.php: new full-featured webhook receiver with signature
  verification, idempotency log, event processing, provisioning trigger
- admin_config.php: expanded to separate sandbox/live fields, computed webhook URL,
  diagnostics panel showing credential status and recent webhook events
- module.php: bumped to v3.3/db_version 3, adds billing_paypal_webhook_events table
