## Explanation

Reduces repo-wide `any` count to 1 (excluding test files).

- Types `provider` variables using the `Provider` type from `@metamask/network-controller`.
  - The `Provider` type is now safe to use, with its recent alignment issues resolved as of MetaMask/eth-query#21.
  - See also MetaMask/core#2028).
- Fixes JSON-RPC typing for provider requests.
  - Installs `@metamask/utils` as a dependency.
- Types `PPOM` variables with provisional skeleton type. 
- Fixes for controller-messenger typing.
- Fixes for misc. `any` usage

## Changelog

### Changed
- Add `@metamask/utils` ^8.3.0 as a dependency. ([#89](#89))

### Removed
- **BREAKING:** `NetworkControllerStateChangeEvent` is removed from the `PPOMControllerEvents` union type. ([#89](#89))

### Fixed
- **BREAKING**: `PPOMController` class constructor option types are narrowed from `any`. ([#89](#89))
  - The constructor expects `provider` to be the `Provider` type from `@metamask/network-controller` (equivalent to `SafeEventEmitterProvider` from `@metamask/eth-json-rpc-provider`).
  - The constructor expects `onPreferencesChange` to be `(callback: (preferencesState: { securityAlertsEnabled: boolean } & Record<string, Json>) => void) => void`.
- **BREAKING:** The `UsePPOM` type replaces `any` with the `PPOM` type in its definition. ([#89](#89))
- **BREAKING:** When a `PPOM` class instance makes JSON-RPC requests to the provider, the `params` type is now widened from `Record<string, unknown>` to `JsonRpcParams`, and the response type is narrowed from `any` to `JsonRpcSuccess<Json>`. ([#89](#89))
