YIR: adds more data needed for native yir

[rectifyer]

Description

Wires the newly-merged Year in Review / Month in Review data expansion into the @trakt/api ts-rest contracts.

Same endpoints (GET /users/:id/yir/:year and GET /users/:id/mir/:year/:month), but the API now surfaces four sections that already existed in the web experience and weren't exposed over the API. The contract's yearInReviewResponseSchema was aliased to monthInReviewResponseSchema, which only modeled stats / images / first_watched / last_watched — so typed clients would never see the new data. This adds them.

New sections

Section	Endpoints	Shape
countries	YIR + MIR	per type (shows/movies): country_count + countries[] of { country, count }
trends	YIR + MIR	per type: up to 12 entries of { month, month_name, watchers, watched, show | movie }
thanks	YIR + MIR	per type: array of { show } / { movie } (popular titles the user hasn't watched)
streaming_services	MIR only	{ country, services[] } with per-service { source, name, shows, movies, all }

• trends.watchers is the global play count; trends.watched is whether this user watched it.
• trends/thanks elements carry a nested show/movie media object with no type discriminator (the type field is only emitted for first_watched/last_watched), so they wrap showResponseSchema / movieResponseSchema directly rather than the typed* variants.
• streaming_services is Month-in-Review only — its catalog scan is bounded to a single month — so it must not appear on the Year in Review shape.

Implementation

• monthInReviewResponseSchema.ts: added countries, trends, thanks, streaming_services. Split out an exported reviewBaseSchema (shared fields + countries/trends/thanks); monthInReviewResponseSchema = reviewBaseSchema + streaming_services.
• yearInReviewResponseSchema.ts: now = reviewBaseSchema (drops the previous plain alias so it excludes streaming_services).
• New section schemas kept inline as private helpers, matching the file's existing convention (statsSchema, watchedItemSchema, …).
• No route, traktContract.ts, or src/index.ts changes — the existing MonthInReviewResponse / YearInReviewResponse type aliases pick up the new fields automatically.
• Bumped @trakt/api to 0.4.15.

Testing

• deno check src/index.ts — passes.
• deno lint + deno fmt --check — clean.
• OpenAPI generate + validate — pass; the generated spec confirms the per-endpoint shapes:

Endpoint	200 properties
GET /users/{id}/mir/{year}/{month}	stats, images, first_watched, last_watched, countries, trends, thanks, streaming_services
GET /users/{id}/yir/{year}	stats, images, first_watched, last_watched, countries, trends, thanks

Checklist

• Clear and concise title
• Detailed description
• Coding standards (deno fmt / deno lint clean)
• Documentation (OpenAPI regenerated & validated)
• Tests — no new contract tests added (consistent with prior contract additions)
