fix(transaction-pay-controller): allow Across perps ETH gas top-up quotes

[pedronfigueiredo]

Explanation

Across perps deposits originating from the PerpsController were being rejected before any quote call when the route included both the USDC deposit leg and the destination-chain ETH gas top-up leg.

The existing Across perps support check only allowed the Arbitrum USDC leg, so the ETH leg triggered quotes-strategy-unsupported and the whole route was rejected locally before reaching Across.

Widen the perps support gate to allow the native ETH top-up leg while still only normalizing the USDC leg into the HyperCore direct-deposit path. This preserves mixed USDC + ETH perps bundles and adds regression coverage for that route shape.

Note

Low Risk
Small, well-scoped gating change limited to perpsDeposit quotes on Arbitrum plus new unit coverage; minimal impact outside this route shape.

Overview
Enables Across perps deposit quote bundles on Arbitrum to include an additional native-token (ETH) gas top-up leg without being rejected as unsupported.

Updates isSupportedAcrossPerpsDepositRequest to accept either the Arbitrum USDC direct-deposit leg or the Arbitrum native-token leg, while normalizeAcrossRequest continues to normalize only the USDC leg to the HyperCore USDC-PERPS route. Adds regression tests for both legs and records the fix in the CHANGELOG.
