feat(money): add a data service which talks to Money Account API

[ffmcgee725]

Explanation

The Earn team currently lacks a dedicated data service for fetching user positions, interest accruals, cash-flow history, and vault rate history from the Money Account API (vertical app hosted at money.api.cx.metamask.io).

This PR introduces @metamask/money-account-api-data-service, a new package that:

• Extends BaseDataService to leverage TanStack Query caching, service policy (retries + circuit-breaking), and messenger integration out of the box.
• Exposes 4 methods via the messenger: fetchPositions, fetchInterest, fetchHistory, fetchRateHistory.
• Uses @metamask/superstruct for runtime response validation, with types derived from structs (Infer<typeof ...Struct>) to prevent type/struct drift.
• Includes detailed validation error messages (superstruct failure details + error cause chain) for easier production debugging.
• Uses fetchInfiniteQuery for the cursor-paginated history endpoint, giving consumers proper TanStack Query pagination semantics.
• Configures retryFilterPolicy to skip retrying validation errors (malformed responses won't fix themselves).
• Supports environment switching (dev / uat / prd) via an Env enum + URL map, following the claims-controller pattern.

This is architected as an independent service. The client calls it directly for API-sourced data, separate from money-account-balance-service which handles RPC-based balance fetching. A future orchestration layer may unify these.

Checklist

• I've updated the test suite for new or updated code as appropriate
• I've updated documentation (JSDoc, Markdown, etc.) for new or updated code as appropriate
• I've communicated my changes to consumers by updating changelogs for packages I've changed
• I've introduced breaking changes in this PR and have prepared draft pull requests for clients and consumer packages to resolve them

Note: No breaking changes introduced — this is an entirely new package (v0.0.0).

Note

Low Risk
New isolated package with no changes to existing controllers; risk is limited to future consumers trusting API-sourced financial display data and external API contract stability.

Overview
Adds @metamask/money-account-api-data-service, a new Earn-team package that fetches vault positions, interest, cash-flow history, and vault rate history from the Money Account HTTP API (separate from RPC-based money-account-balance-service).

MoneyAccountApiDataService extends BaseDataService with TanStack Query caching, messenger actions (fetchPositions, fetchInterest, fetchHistory, fetchRateHistory, invalidateQueries), dev/uat/prd base URLs via Env, and superstruct-validated responses with MoneyAccountApiResponseValidationError (no retries on validation failures). History uses fetchInfiniteQuery for cursor pagination; other endpoints use tuned stale times aligned with server cache TTLs.

Monorepo wiring updates CODEOWNERS, README, teams.json, root tsconfig references, and yarn.lock for the new workspace package.
