treewide: improve release readiness

- Fix E2E tests: rename .spec.ts to .e2e.ts to avoid Playwright/Bun conflict
- Update .env.sample with missing JWT and Resend variables
- Add unit tests for auth, messages, channels, and organizations domains
- Refactor messages/routes.ts (295 lines) into modular route files
- Add structured logging with shared Pino logger instance
