This PR introduces significant new functionality for MUSD (MetaMask USD) conversion and lending features with changes across multiple critical areas:

1. Critical Engine Changes: The earn-controller-init.ts modifies the EarnController initialization to use DEV environment, which is a core controller change.

2. Token Selector Changes: Three critical token selectors (tokenListController.ts, tokenRatesController.ts, tokensController.ts) are modified to add fallback metadata for aTokens (Aave v3 MUSD). These selectors are used throughout the app for token display and pricing, affecting how tokens appear in the wallet.

3. New Confirmation Flows: New confirmation components for lending deposits (LendingDepositInfo) and mUSD max conversion (MusdMaxConversionInfo) are added to the confirmations flow, requiring SmokeConfirmationsRedesigned testing.

4. New UI Screens and Routes: A new MusdQuickConvertView screen is added with new navigation routes for quick convert and max conversion modal.

5. Asset Details Changes: The AssetDetailsActions component changes the "Receive" button to a "Quick Convert" button for mUSD, which is a significant UX change.

6. Feature Flag System: New feature flag selectors for quick convert, CTA tokens, and blocklist/allowlist are added, controlling the visibility of new features.

7. Transaction Monitoring: New useEarnLendingTransactionStatus hook monitors lending transactions and adds tokens to wallet on confirmation.

The risk is HIGH because:

• Core Engine controller is modified
• Token selectors used across the app are changed
• New confirmation flows are added
• UI changes affect asset display and actions
• Multiple new hooks and utilities are introduced

Selected tags cover:

• SmokeStake: Core staking/earning functionality changes
• SmokeConfirmationsRedesigned: New lending and mUSD confirmation flows
• SmokeAssets: Token metadata fallbacks and display changes
• SmokeWalletPlatform: Core wallet functionality with token selectors
• SmokeCore: Engine controller changes and navigation updates
