Implemented email service infrastructure with SMTP support and optional email verification for self-hosted deployments. Registration flow now supports open/closed modes and hardcoded Apocapoc branding. Key features: - Email service with SMTP and template rendering - Optional email verification (auto-verified without SMTP config) - Registration modes: open/closed for access control - Hardcoded Apocapoc branding (AppName, AppURL, DefaultFrom) - Separate registration and login flows (registration no longer returns tokens)
