fix(wallet): Improve default messenger, state and instance types

[FrederikBolding]

Explanation

Infer messenger, instance and state types from defaultConfigurations. Which lets us remove casting due to previous lack of messenger types.

Note

Medium Risk
Mostly TypeScript typing refactors, but it also downgrades @metamask/utils, which could introduce subtle compatibility or build/runtime differences across the wallet package.

Overview
Improves type-safety for the wallet initialization flow by deriving RootMessenger, default action/event types, instance types, and Wallet.state shape directly from defaultConfigurations (new initialization/defaults.ts) and re-exporting them via initialization/index.ts.

Updates Wallet and initialize to use these inferred types (including stricter messenger typing and typed DefaultState/DefaultInstances), removes the old RootMessenger type from types.ts, and adds a couple of targeted @ts-expect-error annotations for calling optional destroy().

Also adjusts sendTransaction to rely on the typed return value from messenger.call (removing an explicit cast) and downgrades @metamask/utils from ^11.11.0 to ^11.9.0 (with lockfile update).
