feat: adds support for custom actions

packages/ramps-controller/CHANGELOG.md

@@ -14,6 +14,10 @@ and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0
 - Added `RampsController:orderStatusChanged` event, published when a polled order's status transitions ([#8045](https://github.com/MetaMask/core/pull/8045))
 - Add messenger actions for `RampsController:setSelectedToken`, `RampsController:getQuotes`, and `RampsController:getOrder`, register their handlers in `RampsController`, and export the action types from the package index ([#8081](https://github.com/MetaMask/core/pull/8081))
 
+### Changed
+
+- **BREAKING:** Replace `getWidgetUrl` with `getBuyWidgetData` (returns `BuyWidget | null`); add `addPrecreatedOrder` for custom-action ramp flows (e.g., PayPal) ([#8100](https://github.com/MetaMask/core/pull/8100))
