Feature: Event tracking for Earn input view currency switch button

  Scenario: user wants to enter fiat amount
    Given user is on EarnInputView (e.g. ETH staking or stablecoin lending)

    When user clicks currency switch
    Then currency switch event is tracked with new `token_symbol` and `chain_id_hex` properties for both ETH staking and stablecoin lending tokens.
