✅ UserBot Integration Complete: Fixed container startup, integrated UserBot menu to main bot

MAJOR FIXES:
✅ Fixed UserBot container startup by making TELEGRAM_BOT_TOKEN optional
✅ Broke circular import chain between app modules
✅ Made Config.validate() conditional for UserBot-only mode
✅ Removed unused celery import from userbot_service.py

INTEGRATION:
✅ UserBot menu now accessible from main bot /start command
✅ Added 🤖 UserBot button to main keyboard
✅ Integrated userbot_manager.py handlers:
   - userbot_menu: Main UserBot interface
   - userbot_settings: Configuration
   - userbot_collect_groups: Gather all user groups
   - userbot_collect_members: Parse group members
✅ UserBot handlers properly registered in ConversationHandler

CONTAINERS:
✅ tg_autoposter_bot: Running and handling /start commands
✅ tg_autoposter_userbot: Running as standalone microservice
✅ All dependent services (Redis, PostgreSQL, Celery workers) operational

STATUS: Bot is fully operational and ready for testing
