fix: pre-select LPT as bridge destination token

[rickstaa]

The "Bridge LPT" menu option (#705) opened the Arbitrum portal with LPT on the source side but ETH on the destination side, because the portal falls back to ETH when destinationToken is absent.

Add destinationToken to BRIDGE_LPT_URL so LPT is pre-selected on both the Ethereum and Arbitrum One sides.

Note: the portal expects the L1 (Ethereum) LPT address for destinationToken and resolves the L2 counterpart internally.

Pull request overview

This PR fixes the “Bridge LPT” deep link so the Arbitrum bridge UI pre-selects LPT on both the source (Ethereum) and destination (Arbitrum One) sides by explicitly providing destinationToken.

Changes:

• Update BRIDGE_LPT_URL to include destinationToken (using the L1 LPT address) so the destination token no longer falls back to ETH.
