feat(domain): Domain\Authors + Domain\Newsletter repositories z wrapper delegation

Phase 4 complete:
- AuthorsRepository: simpleList, authorDetails, authorSave, authorDelete, authorByLang
- NewsletterRepository: 14 methods — subscriber lifecycle, templates, sending
- 4 legacy factories converted to thin wrappers
- Globals ($settings, $lang) passed as explicit params to repo methods
