refactor(services): renale and expand user expand user preference limit service for ugc

Expands the `UserActionLimitService` interface with new, correctly named methods: `checkEngagementCreationLimit` and `checkReportCreationLimit`.

This change correctly frames the limit checks around the primary entities (`Engagement`, `Report`) being created, rather than their sub-components. The `checkEngagementCreationLimit` method now accepts the `Engagement` object to allow for conditional logic based on its content (e.g., presence of a comment).
