> [!NOTE]
> Derives Deposit SDK environment from METAMASK_ENVIRONMENT via new
helper, replaces old flag-based logic, adds tests, and updates Babel
test config exclusions.
> 
> - **Deposit SDK**:
> - **Env resolution**: Introduce
`app/components/UI/Ramp/Deposit/sdk/getSdkEnvironment.ts` to map
`process.env.METAMASK_ENVIRONMENT` to `SdkEnvironment`
(`production|beta|rc` -> `Production`; others/default -> `Staging`).
> - **Usage**: Replace inline env logic in
`app/components/UI/Ramp/Deposit/sdk/index.tsx` with
`getSdkEnvironment()`.
> - **Tests**:
> - Add `getSdkEnvironment.test.ts` covering production, staging,
defaults, and edge cases.
> - **Build/Config**:
> - Update `babel.config.tests.js` to exclude Deposit
`getSdkEnvironment` files from `transform-inline-environment-variables`.
