Enable inbound trigger

Enables the trigger (sets status to active) with provider configuration.

When enabled, webhooks create entities in the backing project automatically.

Provider Configuration Options

1. Set Pipedream provider: {"provider": "pipedream", "provider_metadata": {"trigger_id": "...", "external_user_id": "..."}}

   • Requires both trigger_id and external_user_id in provider_metadata
   • Verifies the deployed trigger exists in Pipedream
   • Deletes remote Pipedream trigger on trigger deletion

2. Set Other/Custom provider: {"provider": "other"}

   • No metadata required for custom webhooks

3. Preserve existing configuration: {} (empty request body)

   • Re-enables trigger with previously configured provider settings
   • Returns error if no provider was previously configured
   • Useful for re-activating a disabled trigger without changing its configuration
