fix(cache-prime): personalize embedded users on three more endpoints (#14367)

## Summary

Three more hooks were priming un-personalized users into the shared user
cache — same bug class as the notifications fix in
[#14366](#14366). API spec
change merged in
[AudiusProject/api#839](AudiusProject/api#839);
this PR consumes it.

| Hook | SDK call | Prime |
| --- | --- | --- |
| `useAllRemixContests` | `events.getRemixContests` | `primeRelatedData`
|
| `useUserRemixContests` | `users.getContestsByUser` |
`primeRelatedData` |
| `useNewAlbumReleases` | `playlists.getPlaylistsNewReleases` |
`primeCollectionData` → `primeUserData` |

In every case the backend handler already calls `app.getMyId(c)` to feed
`MyID` into the `Parallel` query that hydrates embedded users — the
query param just wasn't being sent because the SDK request type didn't
expose it. With no value, `MyID = 0` and the SQL
[short-circuited](https://github.com/AudiusProject/api/blob/main/api/dbv1/get_users.sql.go#L129-L136)
`does_current_user_follow` to false for every embedded user. Clients
then primed those into a shared cache that other surfaces read.

## Changes

| File | Change |
| --- | --- |
| `packages/sdk/src/sdk/api/generated/default/apis/EventsApi.ts` | Add
`userId?: string` to `GetRemixContestsRequest`; map to
`queryParameters['user_id']`. |
| `packages/sdk/src/sdk/api/generated/default/apis/UsersApi.ts` | Add
`userId?: string` to `GetContestsByUserRequest`; map to
`queryParameters['user_id']`. Path field is still `id` (the contest
host); query `userId` is the requester. |
| `packages/sdk/src/sdk/api/generated/default/apis/PlaylistsApi.ts` |
Add `userId?: string` to `GetPlaylistsNewReleasesRequest`; map to
`queryParameters['user_id']`. |
| `packages/common/src/api/tan-query/events/useAllRemixContests.ts` |
Pull `currentUserId` via `useCurrentUserId`; pass as `userId`. |
| `packages/common/src/api/tan-query/events/useUserRemixContests.ts` |
Same. Note this hook already took a `userId` prop for the contest host —
that maps to the path `id`. `currentUserId` is separately threaded as
the query. |
| `packages/common/src/api/tan-query/collection/useNewAlbumReleases.ts`
| Pull `currentUserId`; pass as `userId`. |
| `.changeset/personalization-three-endpoints.md` | Minor `@audius/sdk`
bump for the new optional fields. |

## Note on the SDK files in this diff

I edited the generated `*.ts` files by hand here because `npm install`
in my environment was blocked by a date-pinned registry constraint,
which broke `node_modules` and stopped both `gen.js` and the rollup
build from running. The edits are deterministic — they replicate the
exact pattern openapi-generator already produces for analogous endpoints
(e.g. `GetTrendingPlaylistsRequest` in the same `PlaylistsApi.ts`). A
fresh `npm run gen` on a clean checkout should produce the same diff.
Worth a quick visual confirmation during review.

## Test plan

- [ ] CI green (typecheck/lint/tests).
- [ ] On a fresh app load with a signed-in account: explore → contests
carousel, an artist's contests tab, and browse → new albums all show
correct Following state for surfaced artists without first having to
navigate to each profile.
- [ ] Network inspector on each of the three endpoints carries
`?user_id=<hashed-current-user-id>` and `does_current_user_follow: true`
for users actually followed in `related.users` / collection owners.

+Add an optional `userId?: string` query parameter to three endpoints so the backend can personalize embedded users in `related.users` / collection owners (`does_current_user_follow`, etc.):
+
+- `events.getRemixContests`
+- `users.getContestsByUser`
+- `playlists.getPlaylistsNewReleases`
+
+Without this, the endpoints' handlers (`app.getMyId(c)`) resolved the requester id from the missing `?user_id=` query and got `0`, so embedded user objects came back with `does_current_user_follow: false` for everyone. Clients that primed those into a shared cache (e.g. via `primeRelatedData` / `primeCollectionData`) silently poisoned follow state for the surfaced artists.
+
+Existing callers continue to work unchanged — the field is optional. Pass `Id.parse(currentUserId)` (or whichever id your app treats as "me") to opt in.
