This PR contains significant changes to the mUSD (MetaMask USD) conversion feature within the Earn module:

1. Earn/Staking Changes: Major refactoring of mUSD-related hooks (useMusdCtaVisibility, useMusdBalance, useMusdConversionTokens, useEarnToasts, useMusdConversionStatus), new feature flag selectors, and UI updates to the EarnMusdConversionEducationView. The stake E2E test uses SmokeTrade tag.

2. Token List Changes: TokenListItem.tsx now uses the new useMusdCtaVisibility hook to determine when to show mUSD conversion CTAs. This affects how tokens are displayed in the wallet.

3. Confirmations Changes: New EarningPercentageRow component added to custom-amount-info.tsx for mUSD conversion transactions. This affects the confirmation flow UI.

4. Asset Overview Changes: EarnLendingBalance component updated to use new visibility hooks for mUSD conversion CTAs.

The changes are primarily feature-flag gated (multiple new flags added), which reduces risk. However, the refactoring touches multiple interconnected components in the Earn module and affects token display and confirmation flows.

Selected tags:

• SmokeTrade: The stake test uses this tag, and the Earn module changes could affect staking/trading flows
• SmokeAssets: TokenListItem changes affect asset display in the wallet
• SmokeStake: Direct changes to staking/earn functionality

The version bump and bitrise.yml changes are routine and don't require additional testing beyond what's covered by the functional changes.
