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.
