Replace E2E encryption mentions with privacy-first messaging (#124)
## Summary
- Removes all references to "end-to-end encryption" and "E2E" across the
codebase
- Replaces with privacy-first messaging: data is never shared with third
parties, users own their data, app remains private and secure
- Updates all user-facing content: landing page, onboarding, billing,
terms, emails, setup script, subscription plans, and Coolify template

- Updates `CLAUDE.md` and `README.md` project descriptions
