Note

Medium Risk
Adds a new supported chain across preferences defaults and transaction-related Accounts API/swaps logic; incorrect chain ID mapping or API assumptions could affect transaction history/relationship queries and swaps defaults on that network.

Overview
Adds HyperEVM (0x3e7 / 999) as a supported chain across preferences-controller and transaction-controller.

PreferencesController now includes HYPEREVM in ETHERSCAN_SUPPORTED_CHAIN_IDS and enables it by default in showIncomingTransactions (tests updated accordingly). transaction-controller adds HyperEVM to Accounts API supported chain lists (relationship + incoming transactions), introduces CHAIN_IDS.HYPEREVM, and maps a default swaps token for HyperEVM. Changelogs are updated to reflect the new network support.

@OGPoyraz I had to force-push a CHANGELOG edit, is it possible to reapprove ? 🙏
