fix: hardware wallet eip 7702 issue (cp-7.71.0)

[khanti42]

Description

This PR will provide a fix for hardware wallet to gas free network like Monad and Sei.
Due to currently Hardware wallet is not supported for EIP 7702 gas sponsorship, and Swap feature is not working for hardware wallet user.

This fix will fall back the Gasless transaction to User pay gas previous model so that user can still do the swap and sign transaction like bfore.

This is temporately fix for current version of extensions, and we will do a proper support in the future.

Changelog

CHANGELOG entry: Hardware wallet user will fall back to use User pay gas for those Gasless network due to hardware wallet not supported in Gasless network like Sei and Monad.

Manual testing steps

Feature: Gas sponsorship disabled for hardware wallet accounts

  Scenario: Hardware wallet user does not use gas sponsorship on sponsored network
    Given the user has added a hardware wallet account (Ledger or QR-based)
    And the hardware wallet account is selected as the active account
    And the user has added a gas-sponsored network (e.g. Monad)

    When the user attempts to perform a swap a dapp interaction or send a transaction on the sponsored network
    Then the transaction should not use gas sponsorship
    And the UI should not display any gas sponsorship labels (e.g. "No network fee", "Paid by MetaMask")
    And the user should see the normal network gas fee
    And the transaction should follow the standard user-pays-gas flow

Note

Medium Risk
Touches gasless sponsorship and transaction publishing paths (including 7702 delegation), which can affect whether transactions are sponsored vs user-paid and could change behavior on supported chains. Changes are scoped to hardware-wallet detection gates with added tests, reducing regression risk.

Overview
Hardware wallet accounts now opt out of gasless / EIP-7702 sponsorship, forcing swaps/bridge and confirmations to use the normal user-pays-gas path.

This adds an accountSupports7702 gate to TransactionControllerInit so Delegation7702PublishHook and isEIP7702GasFeeTokensEnabled only activate for keyrings that support 7702, and updates useIsGaslessSupported/useIsGasIncluded7702Supported (via new useIsHardwareWalletForBridge) to report unsupported for hardware signers.

Network selection UI (NetworkSelector, NetworkMultiSelectorList, CustomNetwork) now hides the “No network fee” sponsored label for hardware wallets, and a patched @metamask/bridge-status-controller waits for approval tx confirmation when required. Tests were added/updated to cover the new hardware-wallet gating behavior.
