fix(mobile): Showing videos of partner in search page quick links

[JobiJoba]

Description

Fix issue #18628

I've modified the timeline interface to accept a user Id then modify the timeline repository to check on the user id.
I took the user id in the service which pass down to the repository.

I copy the same behavior than for Favorite but adapted for videos

@override
  Stream<RenderList> watchFavoriteTimeline(String userId) {
    final query = db.assets
        .where()
        .ownerIdEqualToAnyChecksum(fastHash(userId))
        .filter()
        .isFavoriteEqualTo(true)
        .not()
        .visibilityEqualTo(AssetVisibilityEnum.locked)
        .isTrashedEqualTo(false)
        .sortByFileCreatedAtDesc();

    return _watchRenderList(query, GroupAssetsBy.none);
  }

How Has This Been Tested?

• Create an account with one video
• Create another account with one video
• Make them partners
• Check if the videos of partner 2 in the quick links (NO)
• Check if videos of the owner is in the quick links (YES)
