Follow up to #14341.
Promoted content ads views are not limited by maximum_promoted_content_ads_per_hour (default 4) and maximum_promoted_content_ads_per_day (default 20).

Currently, promoted content ads are always shown, but user is paid only once per ad.

Steps to Reproduce

1. Follow Brave Ads maximum promoted content ads per hour - 1 per hour from https://github.com/brave/internal/issues/759
   Or
2. Follow Brave Ads maximum promoted content ads per day - 1 per day from https://github.com/brave/internal/issues/759

Actual result:

Promoted content ads are always shown
Promoted content ads are not limited by maximum_promoted_content_ads_per_hour (default 4) and maximum_promoted_content_ads_per_day (default 20).
User is paid only once per ad.

Expected result:

Promoted content ads are limited by maximum_promoted_content_ads_per_hour and maximum_promoted_content_ads_per_day.

@btlechowski Promoted content ads can be shown unlimited times however users will be rewarded based upon the ads per hour/day settings.

Closing issue as working as expected. Thanks
