## **Description**

This pull request updates the environment handling logic in the
`app/components/UI/Ramp/Aggregator/sdk/index.tsx` module to more
accurately distinguish between production and non-production builds. The
changes improve how the application determines wether Activation Keys
settings are displayed or not and which callback URL to use, refining
the conditions for development and internal builds.

**Environment detection improvements:**

* Added the `Environment` import from the SDK and introduced a new
`isProduction` flag based on the current SDK environment, making
production detection more robust.
* Refactored the logic for `isDevelopmentOrInternalBuild` to include
cases where the environment is not production, ensuring non-production
features are enabled more consistently.

**Callback URL selection:**

* Updated the `callbackBaseUrl` export to use the new `isProduction`
flag, ensuring that the correct callback URL is chosen based on the
refined environment detection.

## **Manual testing steps**

```gherkin
Feature: Buy/Sell Activation Keys

  Scenario: user sets activation keys
    Given the app is a non-prod build

    When user goes to Buy & Sell settings
    Then activation keys UI is displayed

  Scenario: user can't see activation keys
    Given the app is a prod build

    When user goes to Buy & Sell settings
    Then activation keys UI is not displayed
```

<!-- CURSOR_SUMMARY -->
---

> [!NOTE]
> Refines prod/non-prod detection using SDK `Environment`, updates
`callbackBaseUrl` selection, and aligns activation keys gating with the
new logic.
> 
> - **Ramp Aggregator SDK**:
> - Refine environment detection by importing `Environment`, deriving
`environment` via `getSdkEnvironment()`, adding `isProduction`, and
updating `isDevelopmentOrInternalBuild` to include non-production
environments.
> - Switch `callbackBaseUrl` selection to use `isProduction`, choosing
prod vs UAT endpoints accordingly.
> - Initialize SDK with derived `environment` and existing mobile
`context`; keep verbose tied to development.
> - Activation keys gating now follows updated
`isDevelopmentOrInternalBuild` logic.
