* Add installer table-step timeout env vars (MATOMO_INSTALLER_TABLES_CREATION_TIMEOUT_S, MATOMO_INSTALLER_TABLES_ERASE_TIMEOUT_S) to compose/docs and e2e checks.
* **Improved error visibility during Matomo installation**: When the setup fails (for example due to an invalid admin email or missing required fields), the installer now **prints the actual Matomo error messages to the logs**, instead of failing with a generic error.
