Auto-populate Docker .env from existing configuration

Enhanced safe-docker-setup.sh to:
- Auto-detect and copy SESSION, API_ID, API_HASH from existing .env
- Read from environment variables if available
- Show configuration status after setup
- Provide quick start if credentials are found
- Maintain manual setup flow if credentials not found

 Benefits:
- Zero manual configuration if existing setup detected
- Seamless transition from bash startup to Docker
- Immediate ready-to-start Docker environment
- Still preserves existing setup completely
