## Summary by CodeRabbit
## New Features
* Improved edge function webhook authentication by automatically
selecting the appropriate API key or authorization header format.
* Authorization headers are now added or normalized when required, while
preserving existing custom headers and supported credentials.
## Improvements
* Simplified “Add header” and “Add parameter” controls with clearer
labels.
* Updated authentication actions to clearly describe the selected header
type.
## Tests
* Expanded coverage for key formats, authorization behavior, header
preservation, and revised control labels.
