feat: add bridge and swap to HyperEVM (MetaMask#25769)
<!--
Please submit this PR as a draft initially.
Do not mark it as "Ready for review" until the template has been
completely filled out, and PR status checks have passed at least once.
-->
## **Description**
- Adds HyperEVM as selectable network for Bridge/Swap.
- Adds Bridge/Swap feature for HyperEVM (behind feature flags).
- Switches from `CHAIN_IDS` (transactions-controller) to
`NETWORK_CHAIN_ID` (internal, extends `CHAIN_IDS`) in bridge-related
files mapping [chain.id]: { data }. @reviewers happy to discuss about
that and where CHAIN_IDS could be located in the future. I used
`NETWORK_CHAIN_ID` because it already existed and was an extension of
the first one.

<!-- CURSOR_SUMMARY -->
---
> [!NOTE]
> **Medium Risk**
> Adds a new chain into bridge/swap routing via multiple constant maps
and supported-chain allowlists, so incorrect ids/addresses could break
swaps/bridges or mislabel activity. Dependency bumps to
bridge/transaction controllers add some integration risk.
>
> **Overview**
> Enables Bridge/Swaps flows to recognize **HyperEVM** by adding its
chain id to supported network lists, display-name mappings, and
first‑party `Bridge`/`Swaps` contract address maps.
>
> Updates bridge UI defaults by adding a HyperEVM default destination
token (USDC) and treating HyperEVM USDC as a stablecoin for default
slippage logic, while also standardizing several bridge constants to use
`NETWORK_CHAIN_ID` (from `customNetworks`) instead of `CHAIN_IDS`.
>
> Bumps `@metamask/bridge-controller` and
`@metamask/transaction-controller` versions and adjusts unit tests/mocks
accordingly (including using a clearly invalid chain id in a
transaction-history test).
