Security: Fix critical vulnerabilities and implement security hardening

CRITICAL SECURITY FIXES:
- Fixed certificate validation bypass vulnerability in BTCPayServerService
  * Removed unsafe ServerCertificateCustomValidationCallback
  * Added environment-specific SSL configuration
  * Production now enforces proper SSL validation

- Fixed overly permissive CORS policy
  * Replaced AllowAnyOrigin() with specific trusted origins
  * Created separate CORS policies for Development/Production/API
  * Configured from appsettings for environment-specific control

- Implemented CSRF protection across admin panel
  * Added [ValidateAntiForgeryToken] to all POST/PUT/DELETE actions
  * Protected 10 admin controllers with anti-forgery tokens
  * Prevents Cross-Site Request Forgery attacks

CONFIGURATION IMPROVEMENTS:
- Created appsettings.Development.json for dev-specific settings
- Added Security:AllowInsecureSSL flag (Development only)
- Added CORS:AllowedOrigins configuration arrays
- Created comprehensive security roadmap (ROADMAP.md)

ALSO FIXED:
- TeleBot syntax errors (Program.cs, MessageFormatter.cs)
- Added enterprise-full-stack-developer output style

Impact: All Phase 1 critical security vulnerabilities resolved
Status: Ready for security review and deployment preparation

+description: Professional enterprise development with focus on scalability, security, and production-ready solutions
+---
+
+# Enterprise Full-Stack Developer Output Style
+
+You are an enterprise full-stack developer with extensive experience in production systems. Your responses should reflect industry best practices and enterprise-grade solutions.
+
+## Communication Style
+- Use professional, technical language appropriate for enterprise environments
+- Be concise yet thorough in explanations
+- Focus on actionable solutions over theoretical discussions
+- Include relevant context for architectural decisions
+- Use industry-standard terminology and patterns
+
+## Technical Approach
+- Prioritize security, scalability, and maintainability in all solutions
+- Apply SOLID principles and clean code practices
+- Consider performance implications and optimization opportunities
+- Design for enterprise environments (high availability, fault tolerance)
+- Include proper error handling, logging, and monitoring considerations
+- Follow established architectural patterns (CQRS, Repository, Factory, etc.)
+
+## Code Quality Standards
+- Provide production-ready code with comprehensive error handling
+- Include input validation and sanitization
+- Implement proper logging and observability
+- Consider dependency injection and inversion of control
+- Apply defensive programming practices
+- Include relevant unit testing considerations
+
+## Solution Structure
+When providing solutions:
+1. **Architecture Overview**: Brief explanation of the approach and patterns used
+2. **Implementation**: Clean, production-ready code with proper structure
+3. **Security Considerations**: Highlight security implications and mitigations
+4. **Performance Notes**: Identify potential performance impacts or optimizations
+5. **Testing Strategy**: Outline testing approach (unit, integration, end-to-end)
+6. **Deployment Considerations**: Note any production deployment requirements
+
+## Documentation
+- Include inline comments for complex business logic only
+- Provide clear API documentation for public interfaces
+- Document configuration requirements and environment variables
+- Include deployment and operational notes where relevant
+
+## Technology Decisions
+- Prefer established, enterprise-proven technologies and frameworks
+- Consider long-term maintenance and support implications
+- Evaluate licensing and compliance requirements
+- Factor in team expertise and organizational standards
+
+Focus on delivering solutions that would pass enterprise code reviews and perform reliably in production environments with proper monitoring, scaling, and security measures.

+# LittleShop Development Roadmap
+
+## Executive Summary
+
+This roadmap outlines the development priorities and strategic direction for LittleShop, a privacy-focused e-commerce platform with multi-cryptocurrency payment support. The roadmap prioritizes critical security fixes, production readiness, feature enhancements, and long-term scalability.
+
+**Last Updated**: September 19, 2025
+**Version**: 1.1.0
+**Status**: Active Development
+
+---
+
+## 🚨 Phase 1: Critical Security Fixes (IMMEDIATE - September 2025)
+
+### HIGH Priority Security Vulnerabilities
+
+#### 1. ❗ Certificate Validation Bypass [CRITICAL]
+- **Location**: `LittleShop/Services/BTCPayServerService.cs:32-35`
+- **Severity**: HIGH
+- **Impact**: Enables man-in-the-middle attacks on payment processing
+- **Fix Applied**:
+  - ✅ Removed unsafe certificate validation bypass
+  - ✅ Implemented environment-specific configuration
+  - ✅ Added explicit Development-only bypass with warning logs
+- **Timeline**: Immediate - Before any production deployment
+- **Status**: 🟢 COMPLETE (September 19, 2025)
+
+#### 2. ❗ Overly Permissive CORS Policy [HIGH]
+- **Location**: `LittleShop/Program.cs:139-148`
+- **Severity**: HIGH
+- **Impact**: Enables Cross-Site Request Forgery (CSRF) attacks on admin panel
+- **Fix Applied**:
+  - ✅ Replaced `AllowAnyOrigin()` with specific trusted origins
+  - ✅ Implemented anti-CSRF tokens on all state-changing endpoints
+  - ✅ Created separate CORS policies for Development/Production/API
+- **Timeline**: Immediate - Before production deployment
+- **Status**: 🟢 COMPLETE (September 19, 2025)
+
+### Additional Security Hardening
+
+#### 3. ⚠️ CSRF Protection Implementation
+- ✅ Added `[ValidateAntiForgeryToken]` to all Admin controllers
+- ✅ Protected all POST/PUT/DELETE actions (10 controllers)
+- **Timeline**: Week 1
+- **Status**: 🟢 COMPLETE (September 19, 2025)
+
+#### 4. ⚠️ Environment-Specific Configuration
+- ✅ Created appsettings.Development.json with dev-specific settings
+- ✅ Created appsettings.Production.json template
+- ✅ Configured environment-based CORS and SSL settings
+- **Timeline**: Week 1
+- **Status**: 🟢 COMPLETE (September 19, 2025)
+
+---
+
+## 📋 Phase 2: Production Readiness (Q4 2025 - October-December)
+
+### Testing & Quality Assurance
+
+#### 1. Test Coverage Improvement
+- **Current**: 59% pass rate (24/41 tests)
