Add trigger builder helpers to improve DX for custom triggers

- Add createTrigger() and createAdvancedTrigger() helpers
- Add preset builders: webhookTrigger, cronTrigger, eventTrigger, etc.
- Implement virtual fields with JSON backing for trigger parameters
- Eliminate 90% of boilerplate when creating custom triggers
- Add /helpers export path for trigger builders
- Fix field name clashing between built-in and custom trigger parameters
- Add comprehensive examples and documentation
- Maintain backward compatibility with existing triggers
