feat: Expose NetworkController methods through messenger

[cryptodev-2s]

Explanation

Migrates NetworkController to use MESSENGER_EXPOSED_METHODS and registerMethodActionHandlers, replacing manual registerActionHandler calls. The generate-method-action-types script is used to auto-generate action types.

• Adds public getEthQuery() method (replaces lambda accessing private field)
• Exposes 11 previously unregistered public methods as messenger actions
• Deprecates old type aliases missing Action suffix (NetworkControllerGetNetworkConfigurationByNetworkClientId)

Changelog

Added

• 11 new messenger actions: enableRpcFailover, disableRpcFailover, getProviderAndBlockTracker, getNetworkClientRegistry, initializeProvider, lookupNetwork, lookupNetworkByClientId, get1559CompatibilityWithNetworkClientId, resetConnection, rollbackToPreviousProvider, loadBackup

Deprecated

• NetworkControllerGetNetworkConfigurationByNetworkClientId → use NetworkControllerGetNetworkConfigurationByNetworkClientIdAction

Checklist

• I've updated the test suite for new or updated code as appropriate

Note

Medium Risk
Expands and refactors NetworkController messenger action registration and exported types, which can affect downstream consumers’ typing and any code calling these actions. Runtime behavior should be unchanged, but mis-registration or method list drift could break integrations.

Overview
Exposes additional NetworkController methods via the messenger by switching from many manual registerActionHandler calls to registerMethodActionHandlers driven by a centralized MESSENGER_EXPOSED_METHODS list.

Adds an auto-generated NetworkController-method-action-types.ts file (plus a generate-method-action-types script and tsx dev dependency) and re-exports these new action types from index.ts, including new actions like RPC failover toggles and connection/provider lifecycle methods.

Updates assets controllers to import NetworkControllerFindNetworkClientIdByChainIdAction from @metamask/network-controller (removing relative-package type imports) and records the consumer-facing typing fixes in changelogs; removes now-unneeded import-x/no-relative-packages eslint suppressions.
