Refactor database logging to use WordPressDatabaseEntity

Removed DatabaseEntity and LogsRepository classes and their tests. Updated tests to use the new WordPressDatabaseEntity class, including renaming and refactoring the test file. Updated documentation to reflect the new API structure. This change consolidates database logging logic under WordPressDatabaseEntity for improved maintainability.
