Description

Wires up the confirmation UI and post-quote logic so that perpsWithdraw transactions go through the correct gasless HyperLiquid withdrawal flow via Relay.

This is the second of two PRs for Perps Withdraw (follows the first one which added activity/display support).

Changes

• Post-quote config (useTransactionPayPostQuote): Sets isHyperliquidSource = true for perps withdrawals, skips refundTo (funds go HyperCore → Relay directly, no Safe proxy involved)
• Custom amount (useTransactionCustomAmount): Sources available balance from PerpsController.state.accountState.availableBalance for perps withdrawals
• Insufficient balance alert (useInsufficientBalanceAlert): Suppresses the "not enough ETH for gas" alert for perpsWithdraw since the withdrawal is gasless
• Confirmation UI: Adds perpsWithdraw to TRANSACTION_TYPES_DISABLE_ALERT_BANNER, HIDE_FOOTER_BY_DEFAULT_TYPES, and GO_BACK_TYPES
• Bridge fee row: Shows withdraw-specific tooltip text and "Provider fee" label for perpsWithdraw
• Metrics (useTransactionPayMetrics): Includes perpsWithdraw in pay metrics tracking
• TPC bump: Bumps @metamask/transaction-pay-controller to ^19.0.0 which includes the HyperLiquid submission logic

Core dependency

• feat(transaction-pay-controller): add HyperLiquid withdrawal submission via Relay

Manual testing steps

Feature: Perps Withdraw confirmation flow

  Scenario: user withdraws from HyperLiquid Perps to any token
    Given the user has a funded HyperLiquid Perps account
    And the user navigates to the Perps Withdraw page via Developer Options

    When user enters a withdrawal amount
    And selects a destination token (e.g. BNB)
    Then the transaction fee is shown with a tooltip
    And no "Insufficient funds" alert is displayed
    And the available Perps balance is shown correctly

    When user confirms the withdrawal
    Then the withdrawal completes successfully
    And the transaction appears in the Activity list as "Perps withdraw"
