- Added missing i18n keys for integrity and tenant profile pages to root and adminfront locales.
- Corrected i18n section structure in template.toml.
- Fixed Hanmac email policy test by improving tenant hierarchy mocking and ensuring correct CompanyCode propagation.
- Resolved various backend test failures by updating expectations for normalized roles and fixing undefined variables.
